如何base64编码Python脚本

Question

我尝试base64编码python文件，然后将其插入到txt文件中我尝试了以下代码：

import base64

file = open('Python.py', 'r')
txt = open('New.txt', 'wb')
encoded = base64.b64encode(file).read()
txt.write(encoded)
txt.writelines(lines)
file.close()
txt.close()

返回的错误是TypeError：需要类似字节的对象，而不是＆＃39; _io.TextIOWrapper＆＃39;

这是一个简短的Python 3程序，它将任何二进制文件编码为Base64。

base64encode.py

#!/usr/bin/env python3

import base64
import sys

def main():
    if len(sys.argv) != 2:
        print('Encode a file with Base64\nUsage:\n%s filename' % sys.argv[0])
        sys.exit()

    fname = sys.argv[1]
    with open(fname, 'rb') as f:
        data = f.read()

    with open(fname + 'b64', 'wb') as f:
        f.write(base64.encodebytes(data))

if __name__ == '__main__':
    main()

这是在输入自己的源代码（保存为UTF-8）时产生的结果。

base64encode.pyb64

这里有一些反转过程的代码

import base64

with open('base64encode.pyb64', 'rb') as f:
    data = f.read()
with open('newfile', 'wb') as f:
    f.write(base64.decodebytes(data))

结果newfile与base64encode.py

相同
