 . 9  Import html_parser
 10   
. 11  # is not recommended name of the module 
12 is  Import Decoder

 

2, the class name

• Class names use camel (CamelCase) naming style, capitalized, beginning underscore a private class available

1 class Farm():
2     pass
3 
4 class AnimalFarm(Farm):
5     pass
6 
7 class _PrivateFarm(Farm):
8     pass

 

• The related classes and top-level functions in the same module. Unlike Java, a class is not necessary to limit a module.

3, function

• Function name all lower case, if multiple words separated by underscores

1 def run():
2     pass
3 
4 def run_with_env():
5     pass

 

• Private function before the function adds an underscore _

1 class Person():
2 
3     def _private_func():
4         pass

 

4, the variable name

• Try to lowercase variable names, if multiple words separated by underscores

1 if __name__ == '__main__':
2     count = 0
3     school_name = ''

 

• Constant all-uppercase, separated if multiple words, use underscores

1 MAX_CLIENT = 100
2 MAX_CONNECTION = 1000
3 CONNECTION_TIMEOUT = 600

 

5, Constant

• Constant use uppercase names separated by an underscore

1 MAX_OVERFLOW = 100
