Looping in pandas is really slow. I would get the datetime values for two dataframes and process those to create a list of dataframe 2 rows that should be incorporated into dataframe 1. Something li...

You should post your solution so others can benefit. Pygame has lots of support for detecting collisions between things like players and platforms. In the code below I made the player and the platfo...

    Thread: Change a numpy array to a dataframe
Post: RE: Change a numpy array to a dataframe

Why are you using locals()? You should almost never use locals(). Is using locals() some weird conda notebook thing? If you can get locals()[ndarray_name], it means there is a local variable that r...

You should really use pathlib. It is much better than manipulating paths using os. I think you are using glob wrong. Instead of making a pattern that includes the path, I think you should specify t...

You can use numbers like 1e-9 instead of using the pow() function. def equal(a, b, zero=1e-9): return abs(a-b) < zero print(equal(1.1, 1.1)) print(equal(1.1, 1.1 + 1e-8)) print(equal(1.1, 1.1 ...

All possible combinations of 30 items does take a while to compute. It is funny that you expect to print the output. from itertools import combinations items = list('ABCDEFGHIJKLMNOPQRSTUVWXYZ')[:4]...

I would provide a default filename. You can leave this in the code and it will not affect running from the command line. inputFile=sys.argv[1] if len(sys.argv) > 1 else 'default_file'
