What encoding is used in python3

The default encoding in python3 is utf-8. In terms of storage and display, python3 uses text characters and binary data to distinguish, which is more clear and clear.

By default, Python 3 source files are encoded in UTF-8, and all strings are unicode strings. (Recommended learning: Python video tutorial)

Of course you can also specify different encodings for the source code file:

# -*- coding: cp-1252 -*-

Text characters are represented by the str type, and str can represent Unicode All characters in the character set, and binary data is represented by the bytes type.

Conversion between str and bytes

      # bytes object
      b = b"example"
     
      # str object
      s = "example"
     
      # str to bytes
      bytes(s, encoding = "utf8")
     
      # bytes to str
      str(b, encoding = "utf-8")

Uses utf-8 by default

     # bytes object
      b = b"example"
     
      # str object
      s = "example"
      
      # an alternative method
      # str to bytes
      str.encode(s)
     
      # bytes to str
      bytes.decode(b)
