解码base64编码的文件并将结果打印到控制台

Question

So I have a file that I have already encoded with base64, now I want to decode it back but instead of creating another file, I want to decode it in the console and print the results to screen. How to do that?

encoded file string = MUhRRy1ITVRELU0zWDItNlcxSA==

FYI: this would mean first opening the file in console, then decoding the give string

Thanks

Answer 1

Unless I'm overlooking something, this is as simple as reading in your encoded string and then calling the standard library's base64.b64decode function on it.

Something like:

with open(path_to_encoded_file) as encoded_file:
    print base64.b64decode(encoded_file.read().strip())

Using base64.decode , set sys.stdout ( sys.stdout.buffer.raw in python 3.x) as output.

import sys
import base64

with open('filepath') as f:
    base64.decode(f, sys.stdout)
