PEP-8 (more than 15 years old) recommend spaces, so unless you are deliberately looking for a fight, the question is settled.

Autoindent is a solution to a problem that doesn't exist in Python in the first place. Having two independent representations for blocks, one for human readers (indent) and one for compilers (braces), leads to nasty bugs when they get out of sync. Autoindent is a tool to keep them in sync. In Python there is a single representation, so nothing can get out of sync.

But the tooling for editing the code has no support for indenting blocks as trivially as adding braces. Sure, you just run clang-format or such on the block/file, and get all the visual stuff sorted out.

What editor does not support indenting a block? In most editors I know you select the block and hit tab, or shift-tab to outdent.
