I installed ipython through the pip in order to use autocomplete, and now indentation doesn't work in the regular Python shell (it does still work in ipython, though):

>>> def f():
... pass
  File "<stdin>", line 2
    pass
       ^
IndentationError: expected an indented block

I don't understand, you didn't indent pass.

>>> def f():
... pass
  File "<stdin>", line 2
    pass
       ^
IndentationError: expected an indented block
>>> def f():
...     pass
...
>>>

That't the behavior I've always seen from the Python shell.

I shouldn't have to indent it manually; that's what the three dots do (or did, before I installed ipython). But when I hit the Tab button to manually indent it, I still get the indentation error:

Correction: The problem is that I can't indent, because it tries to autocomplete instead.

if you are using any ide, just do ctrl+A and format the code to auto indentation.

If you are using select all the source code block and select source on menu tab and click on fix indentation, your problem will be solved.

That's because you never run ipython.

This start the normal build in interpreter where you have to manually indent.
Start with ipython.
Here python | IPYthon | ptpython(what i use).
Use also cmder it's an whole other class that cmd/powershell rubbish,then get nice color as shown in image under.

I uninstalled iPython and cleaned the registry, but Tab still won't indent.
