Python tips and tricks

Raw

Concatenating a series of lists has quadratic performance. Use itertools.chain() or chain.from_iterable() instead.
With #python iterators, we think of next() as initiating execution. With coroutines, we "await" a downstream event to initiate execution.
Adding %(filename)s and %(lineno)d to the logging format makes it easier to see where log messages came from.
The matrix multiplication operator "@" has the same precedence as multiplication, division, floor division, and remainder.
