encode 和 decode 的使用

txt = '我是字符串'
txt_encode = txt.encode()
print(txt)
# 我是字符串
print(txt_encode)
# b'\xe6\x88\x91\xe6\x98\xaf\xe5\xad\x97\xe7\xac\xa6\xe4\xb8\xb2'
print(type(txt))
# <class 'str'>
print(type(txt_encode))
# <class 'bytes'>
txt_copy = txt_encode.decode( )
print(txt_copy)
# 我是字符串
print(type(txt_copy))
# <class 'str'>

# str->bytes encode
# bytes->str decode
