How to indent in a python program

The syntax of Python is relatively simple, using the indentation method, written The code looks like the following:

# print absolute value of an integer: 
a = 100 
if a >= 0: 
    print(a) 
else:
    print(-a)

The statements starting with # are comments. Comments are for human viewing and can be any content. The interpreter will ignore the comments. Each other line is a statement, and when the statement ends with a colon:, the indented statement is considered a code block.

Indentation has advantages and disadvantages. The advantage is that it forces you to write formatted code, but it does not specify whether the indentation is a few spaces or tabs. As a rule of thumb, you should always use 4 spaces for indentation.

Another benefit of indentation is that it forces you to write less indented code. You will tend to split a long code into several functions to get less indented code.

The disadvantage of indentation is that the "copy-paste" function fails. This is the most annoying thing. When you refactor code, pasted code must be rechecked for correct indentation. Additionally, it is difficult for IDEs to format Python code the same way they format Java code.

Finally, please be aware that Python programs are case-sensitive. If the wrong case is entered, the program will report an error.

Python uses indentation to organize code blocks. Please be sure to follow the convention and stick to the 4-space indentation. In the text editor, you need to set tabs to automatically convert to 4 spaces to ensure that tabs and spaces are not mixed.
