pyc文件反编译转化成py文件

安装uncompyle6

pip install uncompyle6

命令行使用：转化filename.pyc

uncompyle6 -o filename.py filename.pyc

批量转化给定目录下的所有pyc文件

典型案例：pyc文件分布在不同子目录下，我们需要逐层遍历，将每一个pyc文件分别转化成一个同名的py文件。

import os
import sys
def walk_dir(dir,topdown=True):
    for root, dirs, files in os.walk(dir, topdown):
        for name in files:
            if name.endswith('.pyc'):
                part_name = name[0:-4]
                part_file_name = os.path.join(root, part_name)
                print(part_file_name)
                os.system('uncompyle6 -o %s.py %s.pyc'%(part_file_name,part_file_name))

if __name__ == '__main__':
    dirname = "D:\dirname"
    walk_dir(dirname)
