如何将该.py脚本解码为常规代码？

Question

我找到了此代码，并且认为已对其进行了编码。我认为这不是经过编译的字节码，并且看起来不像常规的 .py 脚本。

<ETX>ó
p<NUL>4c[<NUL><NUL><NUL><NUL><NUL><NUL><NUL><NUL><ETX><NUL>

我无法粘贴所有代码，因为其中包含非ASCII字符，因此我将链接附加到GitHub。

我想将文件 dark.py 解码为常规代码，其可读性与以下代码相似：

import sys

    try:
       file = open(file_name, "w")
    except IOError:
       print "There was an error writing to", file_name
       sys.exit()
    print "Enter '", file_finish,
    print "' When finished"
    while file_text != file_finish:
       file_text = raw_input("Enter text: ")
       if file_text == file_finish:
          file.close
          break
       file.write(file_text)
       file.write("\n")
    file.close()
    file_name = raw_input("Enter filename: ")
    if len(file_name) == 0:
       print "Next time please enter something"
       sys.exit()
    try:
       file = open(file_name, "r")
    except IOError:
       print "There was an error reading file"
       sys.exit()
    file_text = file.read()
    file.close()
    print file_text
