RE: Resolving Weekday Schedules to Dates

Do you know of a library that resolves schedules like every Wednesday at 3:00pm to absolute time, that is return the datetime of the next occurrence? It may be as simple, as this to add seven days, assuming a slip of a second is not important or even a hour when things change. Enddate = Beg

Re: Why I fail so bad to check for memory leak with this code?

This naif code shows no leak: import resource import pickle c = 0 while True: pickle.dumps(iter([])) if (c % 1) == 0: max_rss = resource.getrusage(resource.RUSAGE_SELF).ru_maxrss print(f"iteration: {c}, max rss: {max_rss} kb") c += 1 -- https://mail.python.org/

Why I fail so bad to check for memory leak with this code?

I tried to check for memory leaks in a bunch of functions of mine using a simple decorator. It works, but it fails with this code, returning a random count_diff at every run. Why? import tracemalloc import gc import functools from uuid import uuid4 import pickle def getUuid(): return str(uuid

Re: exec() an locals() puzzle
