[转]python str与bytes之间的转换

原文:http://www.cnblogs.com/zqifa/p/python-7.html

# bytes object
b = b"example"

# str object
s = "example"

# str to bytes
sb = bytes(s, encoding = "utf8")

# bytes to str
bs = str(b, encoding = "utf8")

# an alternative method
# str to bytes
sb2 = str.encode(s)

# bytes to str
bs2 = bytes.decode(b)
