本文详细介绍了Python中base64编码和解码的过程，包括将字符串转换为字节字符串，使用base64进行编码和解码，以及如何将解码后的字节字符串转换回原始字符串。并通过示例展示了base64编码在实际场景中的应用。

import base64

copyright = 'Copyright (c) 2012 Doucube Inc. All rights reserved.'

def main():
    #转成bytes string
    bytesString = copyright.encode(encoding="utf-8")
    print(bytesString)

    #base64 编码
    encodestr = base64.b64encode(bytesString)
    print(encodestr)
    print(encodestr.decode())

    #解码
    decodestr = base64.b64decode(encodestr)
    print(decodestr.decode())


if __name__ == '__main__':
    main()

运行结果：
