打印出 Python 脚本中的所有代码 [英] Print out all code in a Python script

问题描述

如何打印出 Python 脚本的内容?

How can I print out the contents of a Python script?

例如，如果我有这个(毫无意义的例子)脚本:

For example, if I have this (pointless example) script:

my_var = 1 + 1
another_thing = "this is my string"

我可以添加什么行来恢复整个内容?

What line can I add to it, to get the entire contents back?

my_var = 1 + 1
another_thing = "this is my string"

# Magically print out all of the code in this file
print .....

推荐答案

打印源代码的程序称为 quines.有几个很好的例子这里.

Programs that print out their source code are called quines. There are a few good examples here.

最简单的方法是读取脚本的源文件:

The easiest way is to read the script's source file:

print open(__file__).read()

如果无法读取文件，则需要将所有代码包装在字符串中.然后您可以执行这些字符串并单独打印它们.

If you can't read from the file, you'll need to wrap all your code in strings. You can then execute the strings and print them separately.
