This article mainly explains "what are the Python programming tips". The content in the article is simple and clear, and it is easy to learn and understand. Please follow the editor's train of thought to study and learn what Python programming tips are there.

1. Orthogonality

Orthogonality is an important principle of programming. In a well-designed system, the database code and the user interface are orthogonal, replacing the database will not affect the user interface, and adjusting the user interface will not affect the database. In practice, keep in mind that An and B should not influence each other, otherwise it is easy to lose control and the system will become unmanageable.

2. Each data is stored in only one place

If you have a piece of data on hand, store it only in one place, not in multiple places. It is best to create a global variable that holds the locale number and save the information in a file or database.

3. The function only does one thing

Limiting a function to only one task has many benefits: first, the function name can directly describe its function, making the code more readable. Second, if the code goes wrong, debugging will be very convenient, because each function is only responsible for a specific task, you can quickly isolate and debug changes.

4. Choose an excellent method

If you come up with the idea of "I've come up with a better idea, but I've started coding and don't want to rewrite it," I suggest you stop immediately and choose the better way you find to do it.

5. Test

Testing is extremely important in a production environment. Programs that are planned to be deployed in a production environment are incomplete until tests are written. Especially if you are writing a program that others will also use, you should write tests.

6. Keep a log

Logging refers to the practice of recording data while the software is running. You can use logs to assist in debugging the program and better understand the state of the program when it is running. Python has its own logging logging module, which supports logging in the console or file.

7. Code review

It is recommended that you review as much code as possible, because even if you follow good practices, there can be errors. So be sure to check the code, find out what's wrong, and fix it. Or you can use a programmer community like Code Review for code review.

8. Security

Security is an issue that is easy to be ignored, but in fact we need to be directly responsible for the security of our code, so it is best not to use sudo to execute commands on the command line; in addition, we should assume that the user's input is malicious, so as to guard against it to a large extent; second, to minimize the attack area, that is, hackers can extract data from the program or attack the relevant areas of the system. In short, try to think from a hacker's point of view: how will they use your code? Try to find loopholes that may be overlooked.

9. Use powerful IDE

It is usually encoded using the IDE--IDLE that comes with Python. But in fact the function of IDLE is limited. Therefore, it is recommended to use a more powerful IDE to ensure the quality of your code. As for the easy-to-use IDE, the editor has introduced it, you can refer to the previous article.

10. Summary of terms

Production: putting software into production, which refers to the official release to the outside world.

DRY: a programming principle, short for "Don't repeat yourself".

Orthogonality: indicates some kind of independence or decoupling. If the changes between two or more things do not affect each other, then there is orthogonality between them.

Debugger: a debugger is a program that supports interrupting code execution and viewing the effect of the code line by line. Through the debugger, we can view the values of variables in different code.

Logging: refers to the practice of recording data while the software is running.

Testing: check whether the program meets the design and development requirements, return the correct results for all kinds of inputs, the function execution is time-consuming, and the availability is high enough to install and run in the target environment, and achieve the desired results of the relevant stakeholders.

Code review: the process of reading code and giving feedback.

Attack area: hackers can extract data from the program or attack the relevant areas of the system.
