"""
bytes(iterable_of_ints) -> bytes

bytes(int) -> bytes object of size given by the parameter initialized with null bytes

Construct an immutable array of bytes from:
- an iterable yielding integers in range(256)
- a text string encoded using the specified encoding
- any object implementing the buffer API.
- an integer

Python中的字节码用b‘xxx‘的形式表示。x可以用字符表示，也可以用ASCII编码形式\xnn表示，nn从00-ff(十六进制)共256种字符。
a = ‘abc‘ b = bytes(a, ‘utf-8‘) print(b) c = bytes(a, ‘gbk‘) print(c) # 结果 b‘abc‘ # 结果 b‘abc‘ a = ‘你好‘ b = bytes(a, ‘utf-8‘) print(b) c = bytes(a, ‘gbk‘) print(c) # 结果 b‘\xe4\xbd\xa0\xe5\xa5\xbd‘ # 结果 b‘\xc4\xe3\xba\xc3‘
decode
c = bytes(a, ‘gbk‘).decode(‘gbk‘) print(c) # 结果 你好
