Do projects exist to audit PyPI-hosted packages?

I woke with a start in what amounted to the middle of the night (I really need to get about three more hours of sleep, but you'll understand why I was awake to write this). Many years ago, so as to preserve my wrists, I wrote a tool

Re: Python/New/Learn

This topic has rapidly shifted over way beyond Python even as the original  person has not returned to participate. There are many ways to teach anything and since the classical method was to learn in person from someone using mainly sound or pantomime, it has hung on. Even with the existence of

Seeking deeper understanding of python equality (==)

Hi, I was recently trying to explain how python equality works and ran into a gap in my knowledge. I haven't found any good pages going beneath a surface level explanation of python equality comparison. I'll post my investigations below. What I think I'm looking for is where in the source code (h

pandas (in jupyter?) problem

Hi all! I'm having the following problem. Consider the code (the commented or the not commented which I think do the same things): #for col in missing_cols: #df[col] = np.nan df=df.copy() df[missing_cols]=np.nan df has about 2 cols and len(missing_cols) is about 18000. I'm getting l

Re: tail

I have a little problem. I tried to extend the tail function, so it can read lines from the bottom of a file object opened in text mode. The problem is it does not work. It gets a starting position that is lower than the expected by 3 characters. So the first line is read only for 2 chars, and th
