lot of copied variables, because of c I suppose? Things like var = self.var
If we're very charitable, there's a micro-optimization w/ Python (or at least, older Python) where assigning to a local variable like this inside a method is faster than the full self.var lookup, so you'll see it in Python's library code while setting up some loops, etc. as a small speedup. "lots of copied variables", though, is likely an anti-pattern if not in a heavily used piece of library code, imo.
What's really crazy is when people write modified Python language pre-processors where:
var = var
is a necessary thing (to bring the var into the right context for the pre-processor to recognize it; yes, I've seen this...)
