Python Ranks #1 in IEEE “Top Programming Languages”
“Python dominates as the de facto platform for new technologies” and “Learn Python. That’s the biggest takeaway we can give you from its continued dominance of IEEE Spectrum’s annual interactive rankings of the top programming languages. You don’t have to become a dyed-in-the-wool Pythonista, but learning the language well enough to use one of the vast number of libraries written for it is probably worth your time.”

math.sqrt vs numpy.sqrt vs x ** 0.5 Performance Discussion
Andrej Karpathy (Director of AI at Tesla) shares an interesting performance observation on this Twitter thread that turns into a tale about accurate benchmarking. Calculating math.sqrt(1337.0) appears to be 10x faster than numpy.sqrt(1337.0). Python’s built-in square root (x ** 0.5) appears to be even faster. However, most of the performance differences seem to come from the benchmark setup, as Ishan Bhatt explains in this writeup.
