Speed is only important when you’re writing something that’s very computation-intensive or will be run many many times .

Python is a more semantically powerful, high-level language than faster languages, which makes it much quicker and less painful to develop in . It’s for the same reasons that it’s so semantically powerful that it’s so slow: it must be interpreted because the language is too dynamic to be statically compiledFeb 08 2021
