This article introduces the relevant knowledge of "what are the Python novice training projects?". In the operation of actual cases, many people will encounter such a dilemma. Next, let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!

Content aggregator (Content Aggregator)

Technical details

The main goal of the project design is to aggregate content. First, we need to know which sites the content aggregator gets content from. Then, use the request library to send the HTTP request, and use BeautifulSoup to parse and crawl the necessary content of the site.

The application can implement its content aggregation as a background process. Libraries such as celery or apscheduler can help. It is recommended to try apscheduler. It is very suitable for small background processes.

Content crawled from various sites needs to be saved. Therefore, a database is required.

Regular expression query tool

1. Technical details

The main purpose of such projects is to determine the validity of the query string entered by the user. You can let it give valid and invalid discrimination, such as "query string is valid" and "query string is invalid", valid in green and invalid in red.

You don't have to build a query tool from scratch. Using Python's standard relibrary, you can run a query string on the entered text. When the query string does not match, the re library returns None, and when it does, it returns the matching string.

Some users may not fully understand regular expressions, so readers can create their own page to explain how regular expressions work. Write a document that is interesting enough to make users interested in learning and understanding regular expressions.

two。 Additional Challen

It's good to make a project that only returns the validity of regular expressions. However, you can also add replacement functions. This means that the application will check the validity of the regular expression and allow the user to replace the matching string with something else. Therefore, the tool is no longer just a query tool, but also a replacement tool.

URL shortening (URL Shortener)

1. Technical details

The main goal of the project design is to shorten the URL. After shortening the URL, the application redirects the user to the original URL when accessing the shortened URL.

In the application, the user enters the original URL and ends up with a new shortened URL. To do this, you can use a combination of random and string modules to generate characters for a shortened version of URL.

Because users will access the shortened URL in a few days, months, or even years, you need to keep the original URL and the shortened URL in the database. When a request occurs, the application checks for the existence of the URL and redirects to the original URL, otherwise it redirects to the 404 page.

two。 Additional Challen

Using random characters to generate shortened URL is better than URL with long random characters. By adding functionality to customize the URL, users can customize the generated URL.

There is no doubt that custom xyz.com/mysite URL is better than randomly generated xyz.com/piojwr URL.

Post-it note function

1. Technical details

The main purpose of the project is to get users to write down their thoughts. That is, each user has his own notes, so the application needs to have account creation capabilities. This ensures that each user's notes are private.

Django comes with a user authentication system, so it may be a good choice. You can use other frameworks, such as bottle and flask, but you must implement your own user authentication system.

Because users may need to record different notes in different situations, implementing the user's note classification function will make the application more practical.

For example, you may need to record some algorithms and data structures, so you need to divide different notes into their own categories.

You need to store each user's information and notes, so the database becomes an important part of the project. If you want to use the MySQL database or the psycopg2 module for the PostgreSQL database, you can use the MySQLdb module. You can also use other modules, but it all depends on the database you choose to use.

two。 Additional Challen

It's only natural for users to forget what they think, and sometimes even forget to take notes. You can add a feature to remind users that they have taken notes. This feature allows the user to set the reminder time, and the application will remind the user via email.

Test

1. Technical details

The main goal of this project is to set up tests and get people to answer them. Therefore, users should be able to set questions, and other users should be able to answer them. The application then displays the final score and the correct answer.

If you want users to be able to record their scores, you need to implement account creation.

Users who create tests should be able to create tests with questions and answers by uploading text files. The text file should be able to be converted to the format the user needs, so the application can convert the file to the quiz format.

You also need to create a database for this project. The database stores each user's questions, possible answers, correct answers, and scores.

two。 Additional Challen

You can allow users to add timers to the quiz. In this way, the creator of the quiz can determine how long the user spends on each question in the quiz.

It's also great to have test sharing so that users can share interesting quizzes with their friends on other platforms.

GUI Project Design MP3 player

1. Technical details

The main goal of the project is to allow users to play MP3 and digital audio files. In order to attract users, applications must have a simple but beautiful user interface.

You can add an interface that lists available MP3 files. You can also list other non-MP3 digital audio files for the user.

Users also want the MP3 player to have an interface that displays information about the file being played. This can include the file name, length, playback time, and unplayed time (in minutes and seconds).

Python has libraries that can play audio files, such as pygame, and can process multimedia files in a few lines of code. You can also view pymedia (https://pypi.org/project/PyMedia/) and simpleaudio).

These libraries can handle a large number of digital audio files. Includes MP3 files and audio files in other formats.

In addition, these libraries have features that allow users to create playlists. To do this, you need a database to store information about the playlists you created. The sqlite3 module of Python allows the use of SQLite databases.

In this case, the SQLite database is a better choice because it is file-based and easier to set up than other SQL databases. Although SQLite is file-based, it can save data better than regular files.

two。 Additional Challen

If all of the above is done, you can also add a feature that allows the MP3 player to repeat the file that is currently playing, or even play it randomly.

You can also add the ability to increase and decrease the playback speed of audio files. Users will like this feature because they can play audio files more slowly or faster than usual.

Alarm reminder tool

1. Technical details

The main goal of the project is to activate audio signals at specific times of the day. Therefore, timing and audio signal playback is the most important part of the alarm tool.

The alarm tool should allow users to create, edit, and delete alarms. It should also have an alarm interface that lists all the alarms that have not been deleted. Therefore, it should list activity alarms and idle alarms.

Because it is an alarm, the application must play audio at a specified time. The libraries used to play audio are pygame libraries and so on.

In code logic, the application must constantly check the set alarm time. After arriving at the time, it will trigger a function to play the alarm clock tone.

Because the application will check the set alarm time, this means that the application must save it in the database. The database should store alarm date, time and audio.

two。 Additional Challen

You can also allow users to set periodic alarms. The user can set the bell to ring on certain days of the week and at a specific time. For example, you can set the alarm at 2:00 every Monday afternoon.

You can also add a pause feature so that users can pause the alarm clock instead of deactivating it.

File Manager

1. Technical details

The main goal of the File Manager project is to provide users with an interface for managing files. Users need an easy-to-use and practical file manager.

You can use the PySimpleGUI library to create a user interface with a powerful widget that doesn't have to deal with a lot of complex work.

Users should be able to perform simple tasks, such as creating new directories or empty text files. You should also be able to copy and move files or directories.

The sys, os, and shutil libraries are useful for this project and can be used to perform operations on the stage when the user clicks.

Grid view and list view are currently popular views, so you can implement both views in your application. Users can choose the view options that suit them.

two。 Additional Challen

To make the file manager more advanced, you can add the search function. Users can search for files and directories without having to find them manually.

In addition, sorting can be implemented. Users sort files in different order, such as time, alphabetical order, or size.

Bookkeeping function

1. Technical details

The main goal of the project is to track users' expenses. In order to provide users with correct information and help them optimize their spending, some statistical analysis is needed.

While tracking costs is key, a good interface is also important. With PySimpleGUI, you can create a unique interface to improve the user experience.

PyData libraries such as pandas and matplotlib can help you design accounting tools.

The pandas library can be used for data analysis, and the matplotlib library can be used to draw graphics. The chart will provide users with a visual representation of their expenses, and visualization is usually easier to understand.

The application will get the data from the user. The data here is the input expenditure. Therefore, the cost needs to be stored in the database. The SQLite database is a good choice for this project because it can be set up quickly. You can use the sqlite3 module for SQLite databases.

two。 Additional Challen

In order for users to benefit from this project, they need to enter their own expenses in the application on a regular basis, but people may often forget. So adding a reminder function is very effective. In this way, the application sends notifications at a specific time of day or week to remind users to use accounting tools.

Command line project design address book

1. Technical details

The main goal of the project is to save contact information. It is important to set commands that allow users to enter contact details. You can use the argparse or clickcommand-line framework. They simplify a lot of complex things, so you only need to focus on the logic to run when the command is executed.

In addition, there are some functions that need to be implemented, such as deleting contacts, updating contact information, and listing saved contacts. You can also allow users to list contacts in a different order, such as alphabetical order or contact creation date.

It is a command line project, and contacts can be well saved with the SQLite database. The setting of SQLite is very friendly. You can save contact details in a file, but the file will not have the advantages of SQLite, such as better performance and security.

The Python sqlite3 module will be very useful to use the SQLite database in this project.

two。 Additional Challen

Remember how the database is stored on the user's computer? What happens if the user file is lost? This means that they will also lose their contact information.

A further challenge is to back up the database to the online storage platform. To do this, you can upload database files to the cloud at specific intervals.

You can also add commands that allow users to back up the database themselves. In this way, if the database file is missing, the user can still access the contact.

It should be noted that you may need some form of identity so that the address book can identify which database file belongs to which user. Implementing the user authentication function is one way to achieve this function.

Website connection check

1. Technical details

The main goal of the project is to check the status of the website. Therefore, you need to write code to check the status of the Web site.

You can choose to use TCP or ICMP to connect. The socket module is a module for checking. You can also read socket programming in the Python guide.

Whether it's the docopt, click, or argparse framework, you can add commands that allow users to add and remove sites from the list of sites to check.

Users should also be able to start the tool, stop the tool, and determine the interval.

Because we have to save the list of files to check, we can save them in the file (just a list of websites), or we can use the SQLite database through the sqlite3 module.

two。 Additional Challen

The application can also check the connection status of the site and display the results on the command line. However, this requires the user to continue to check the command line.

The notification function can also be added. The notification function can remind the user by voice in the background when the status of the site changes. You need a database to store the previous status of the site. This is the only way the tool can tell when the state changes.

Batch File renaming tool

1. Technical details

The main goal of this project is to rename the file. Therefore, the application needs to find a way to manipulate the object file. The os, sys, and shutil libraries are useful for this project.

Your users will be able to rename all files in the directory using the naming convention. Therefore, they should be able to develop their own naming conventions. If you understand how regular expressions work, the regex module can help match the naming patterns you need.

You may want to pass a naming convention (such as myfiles) as part of the command and expect the tool to rename all files, such as myfilesXYZ, where XYZ is a number. They should also be able to choose the directory where the file to be renamed is located.

two。 Additional Challen

The main challenge for this project is to rename all files in the directory. But the user may only need to name a certain number of files. So you can implement a feature that allows users to choose the number of files to rename instead of all files.

Note that renaming only a certain number of files will require the tool to sort files according to alphabetical order, file creation time, or file size, depending on the user's requirements.

Directory Tree Generator

1. Technical details

The main goal of the directory tree generator is to visualize the relationship between files and directories. The os library is useful for listing files in directories and selected directories.

Frameworks such as docopt or argparse simplify a lot of content, allowing you to focus on writing code for the logic of your application.

In the logic of the application, you can decide how to represent files or directories. Using different colors is a good way. You can use the colored library to print files and directories in different colors.

You should also be able to set the depth of the directory tree generator. For example, if the subdirectory of a directory has 12 levels, and you only need to use the fifth level.

If you prefer, you can also let the user decide the depth of the directory tree generator.

two。 Additional Challen

Since the result of the generated directory tree will appear on the command line, you can go a step further and let the generator create an image of the directory tree, that is, the operation of converting text to image.
