That's easy to say. How do you actually ensure that they aren't mixed?
The software may not highlight the difference.
Python 3 will tell you immediately, since it forbids
mixing tabs and spaces.

File "<stdin>", line 3

So I still think it's fragile, meaning you have to take a lot of extra
care.
The practical experience of a very large number of Python
programmers suggests that it requires very little additional
care over and above that normally required for programming.
What's your experience? How often has this caused you trouble,
and what proportion is it of all the Python programming you've
done?
