python3中使用什么编码

# -*- coding: cp-1252 -*-

# bytes object

b = b"example"

# str object

s = "example"

# str to bytes

bytes(s, encoding = "utf8")

# bytes to str

str(b, encoding = "utf-8")

# bytes object

 b = b"example"

 # str object

 s = "example"

 # an alternative method

 # str to bytes

 str.encode(s)

 # bytes to str

 bytes.decode(b)
