I don't know about that. I've never screwed up identaton so much that I couldn't correct it simply by selecting everything I just pasted and hitting tab a couple times in my IDE (PyCharm). Similarly, copying code from StackOverflow, Github and random blogs have all worked without any issues. So it can't be as easy as you imply.
