Damn it Time Patrol! You can't stop me!

I've heard similar from the worst first year CS students you could ever meet. People talk out their ass without the experience to back up their observations constantly. The indentation thing is a reasonable heuristic that states you are adding too much complexity at specific points in your code that suggests you should isolate core pieces of logic into discrete functions. And while that's broadly reasonable, this often has the downside of you producing code that has a lot of very small, very specific functions that are only ever invoked by other very small, very specific functions. It doesn't make your code easier to read or understand and it arguably leads to scenarios in which your code becomes very disorganized and needlessly opaque purely because you didn't want additional indentation in order to meet some kind of arbitrary formatting guideline you set for yourself. This is something that happens in any language but some languages are more susceptible to it than others. PEP8's line length limit is treated like biblical edict by your more insufferable python developers.
