Python 中字节与字符串的转换
#bytes object
byte = b"byte example"
# str object
str = "str example"
# str to bytes 字符串转字节
bytes(str, encoding="utf-8")
# bytes to str 字节转字符串
str(bytes, encoding="utf-8")
# an alternative method
# str to bytes 字符串转为字节
str.encode(str)
# bytes to str 字节转为字符串
bytes.decode(bytes)
例子
str = '你好'
bytes_param = str.encode('utf-8')
print(bytes_param, type(bytes_param))
str = bytes_param.decode('utf-8')
print(str, type(str))
