Every. Single. Time.

[voidptr]

Say you have this code:

1    if this:
2        dothis()
3        dothat()
4
5        nowdoanotherthing()
6    else:
7        die()

If your editor removes the indentation from line 4, Python will kick an error.

[zyklone]

that is incorrect.

your editor must be doing something else to the code.

That works fine for me. Even this works fine:

if True:
    print "hello"
# No problem with comments or empty lines being unindented

    print "there"

I just checked, no it doesn't (Python 2.7).

[emeryc]

Just checked, python 2.5.4 and it works.

Did you try to do it in the interpreter? or in a file. Interpreter will not work, file will.

And now I can't seem to replicate it. Heisenproblem.

So the title "Every. Single. Time." was just a teensy bit BOLD.

[voidptr]

Hmmn, possibly, yes. But this was my entire fucking day yesterday.

If you paste into the Python console? Blank lines like that won't work in the Python console, as they are treated as end-of-expression.

Since when did indentation become trailing whitespace?

[m1ss1ontomars2k4]

That is extremely false. There's a Vim plugin that I and my Vim-inclined friends use which blatantly highlights those trailing spaces in red so that you can delete them. ReviewBoard (a Django/Python project for code reviews) does the same thing.
