Too bad. Well then don't use code from people using TABs. If it's indented by four spaces per level, like suggested by the style guide, there's no problem with TABs.

As the indentation *is* significant in python, none of the above can help if you lose the indentation.

Sure -- but a heuristic that gets it right *sometimes* may still be useful, provided the user knows that the code may not be indented correctly. There are lots of legal Python blocks where the indentation CAN be reconstructed correctly, and only a relatively small proportion where it can't -- the tool could do its best, and warn the user when there are indents that can't be dealt with. Or even refuse the temptation to guess, but re-indent whatever parts of the code it is sure about.

Sure -- but a heuristic that gets it right *sometimes* may still be useful, provided the user knows that the code may not be indented correctly. There are lots of legal Python blocks where the indentation CAN be reconstructed correctly, and only a relatively small proportion where it can't -- I'd say absolutely the opposite. Try the example above. Or this one, simpler: def foo(): if a0: if b0: print 1 print 2 Which level should be 'print 2' assigned to? There are 3 choices. What if there is a third print? There are 3, 2, or 1 possibilities, depending on where you put the previous one. The same for any other statement below. The problem is, after a colon, you know that a new block begins and you must indent, but you don't know when that block ends except in a few cases (an else clause, by example, and only if there was a single preceding if). the tool could do its best, and warn the user when there are indents that can't be dealt with. Or even refuse the temptation to guess, but re-indent whatever parts of the code it is sure about. ...almost nothing, I'm afraid... :( Still, it is better not to lose the indentation in the first place.
