python 字节bytes和字符串string的转换

原文：https://www.cnblogs.com/skiler/p/6687337.html

import hashlib

#字节对象b
b = b"example"
#字符串对象s
s = "example"
print(b)
print("example")

字符串->字节

b2 = bytes(s,encoding='utf8')  #必须制定编码格式
# print(b2)

b3 = str.encode(s)
print(b3)
print(type(b3))

b4 = s.encode()
print(b4)

字节->字符串

#将字节对象decode将获得一个str对象
s2 = bytes.decode(b)
print(s2)

s3 = b.decode()
print(s3)
