Any reason not to use ‘+’ to concatenate two strings?
A common antipattern in Python is to concatenate a sequence of strings using + in a loop. This is bad because the Python interpreter has to create a new string object for each iteration, and it ends up taking quadratic time. (Recent versions of CPython can apparently optimize this in some cases, but other implementations can’t, so programmers are discouraged from relying on this.) ''.join is the right way to do this.
