Python code specification and naming conventions

1. Module

• The module uses lowercase names as much as possible, keeping the first letter lowercase and trying not to underline (unless there are multiple words and a small number of cases)

# 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 the Hump (CamelCase) naming style, capitalized, and the private class can start with an underscore

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

• Place related classes and top-level functions in the same module. Unlike Java, there is no need to restrict a module to a class.

3. Functions

• Function names are lowercase, if there are multiple words, separated by underscores

def run(): passdef run_with_env(): pass

• The private function adds an underscore before the function _

class Person(): def _private_func(): pass

4. Variable name

• Variable names are as lowercase as possible, with multiple words, separated by underscores

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

• Constants are all uppercase, if there are multiple words, separated by underscores

MAX_CLIENT = 100MAX_CONNECTION = 1000CONNECTION_TIMEOUT = 600

5. Constants

• Constants are named with an underscore-delimited capitalization

Max_overflow=  -Class FooBar:   def   foo_bar( Self  ,   print_):   print (   Print_)
