I'm embarrassed to ask, is there any way to make it more "pythonic" ie condense it while making it (more) readable? Switching functions is fine; I'm only interested in readability. Thanks from math import sqrt def isprime(n): if n ==2: ...

How can I pick tags from an article or a user's post using Python? Is the following method ok? Build a list of word frequency from the text and sort them.

Hey guys, this is my first question here on Stack Overflow and I was wondering if I could ask the advice of people who know a bit more about Python and Parser Generators than I do.

Dear SO, I'm trying to write an implementation of Wilson's spectral density factorization algorithm [1] for Python. The algorithm iteratively factorizes a [QxQ] matrix function into its square root (it's sort of an extension of the Newton-Raphson square-root finder for spectral density matrices). The problem is that my implementation o...
