This article is about how Python uses the underscore naming convention. Xiaobian thinks it is quite practical, so share it with everyone for reference. Let's follow Xiaobian and have a look.

description

A single preunderlined_var for internal purposes.

Use var_when you want to use Python keywords as variables in your code.

Double pre-underscore is used for name modification__var.

Double underscore (before and after) is used for method name__var__.

Example 1

def _test_func(): Return 20_test_func()

output

20

Example 2

def test_function(list_): return list_* 2test_function([1,2,4,5])

output
