python怎么引用多行输入,如何删除Python三重引用多行字符串的额外缩进？

I have a python editor where the user is entering a script or code, which is then put into a main method behind the scenes, while also having every line indented. The problem is that if a user has a multi line string, the indentation made to the whole script affects the string, by inserting a tab in every space. A problem script would be something so simple as:

"""foo

bar

foo2"""

So when in the main method it would look like:

def main():

"""foo

bar

foo2"""

and the string would now have an extra tab at the beginning of every line.

So if I get it correctly, you take whatever the user inputs, indent it properly and add it to the rest of your program (and then run that whole program).

So after you put the user input into your program, you could run a regex, that basically takes that forced indentation back. Something like: Within three quotes, replace all "new line markers" followed by four spaces (or a tab) with only a "new line marker".
