Python中字符串與字節之間相互轉換

​

a = b"Hello, world!"   # bytes object
b = "Hello, world!"    # str object

 

字符串轉字節 str --> bytes

# 字符串轉字節  str --> bytes
print(str.encode(b))  # 默認 encoding="utf-8"
print(bytes(b, encoding="utf8"))
print(b.encode())      # 默認 encoding="utf-8"

 

字節轉字符串 bytes --> str

​# 字節轉字符串  bytes --> str
print(bytes.decode(a))   # 默認encoding="utf-8"
print(str(a, encoding="utf-8"))
print(a.decode())       # 默認 encoding="utf-8"
