What are the naming rules of python language?

Python language naming rules:

1. Module:
Try to use lowercase names for modules, with the first letter Keep it lowercase and try not to use underscores (unless there are multiple words and a small number).

# 正确的模块名import decoderimport html_parser
# 不推荐的模块名import Decoder

2. Class name:
The class name uses CamelCase naming style, with the first letter capitalized. Private classes can start with an underscore.

class Farm():
    pass
class AnimalFarm(Farm):
    pass
class _PrivateFarm(Farm):
    pass

3. Function:
Function names must be lowercase. If there are multiple words, separate them with underscores.

def run():
    pass
def run_with_env():
    pass

Private functions add an underscore_ before the function.

class Person():
    def _private_func():
        pass

4. Variable name:
Variable names should be in lowercase letters. If there are multiple words, separate them with underscores.

if __name__ == '__main__':
    count = 0 
    school_name = ''

5. Constants:
Constants are named in uppercase letters separated by underscores.

MAX_OVERFLOW = 100
Class FooBar:
    def foo_bar(self, print_): 
        print(print_)

It is recommended not to use == for Boolean comparisons.

# Yes
if greeting::
   pass
# Noif greeting == True
   pass
if greeting is True: 
# Worse
  pass
