This article mainly explains the "introduction to Python to master what basic knowledge", the content of the explanation is simple and clear, easy to learn and understand, the following please follow the editor's ideas slowly in-depth, together to study and learn "what basic knowledge to be mastered in the introduction to Python"!

1.Python variable type

The value of the variable stored in memory. This means that a space is opened up in memory when you create a variable. Based on the data type of the variable, the interpreter allocates the specified memory and determines what data can be stored in memory. Therefore, variables can specify different data types, and these variables can store integers, decimals, or characters.

2.Python string

Strings are the most commonly used data type in Python. We can use quotation marks ('or ") to create a string. Creating a string is as simple as assigning a value to a variable.

3.Python tuple

Tuples in Python are similar to lists, except that the elements of tuples cannot be modified. Tuples use parentheses and lists use square brackets. Tuple creation is simple, just add elements in parentheses and separate them with commas.

4.Python list (List)

Sequence is the most basic data structure in Python. Each element in the sequence is assigned a number-its position, or index, with the first index 0, the second index 1, and so on. Python has built-in types for six sequences, but the most common are lists and tuples. Operations that can be performed in a sequence include indexing, slicing, adding, multiplying, and checking members.

In addition, Python has built-in methods to determine the length of the sequence and to determine the largest and smallest elements.

The list is the most commonly used Python data type and can appear as a comma-separated value in square brackets. Data items in a list do not need to have the same type to create a list, just use square brackets to enclose different data items separated by commas.

5.Python date and time

Python programs can process dates and times in many ways, and converting date formats is a common feature. Python provides a time and calendar module that can be used to format dates and times. The interval is a floating-point decimal in seconds. Each timestamp is expressed in terms of how long has elapsed since midnight on January 1, 1970. There are many functions under Python's time module that can convert common date formats.

Thank you for your reading, the above is the content of "what is the basic knowledge to be mastered in the introduction to Python". After the study of this article, I believe you have a deeper understanding of what basic knowledge to be mastered in the introduction to Python, and the specific use needs to be verified in practice.
