How to properly create a timed loop?
📁 Advanced Python Topics
I need to create a loop that will execute a function for one minute with a 1-second interval.
What is the most efficient way? I couldn't think of anything better than this:
from time import sleep seconds_left = 60 while seconds_left > 0: do_something() seconds_left -= 1 sleep(1)I found a pretty elegant way to rotate a matrix in one line without numpy and loops. Couldn't find anything decent in Russian resources, maybe it will help someone. Original here:
rotated = zip(*original[::-1]) # Python 2rotated = tuple(zip(*original[::-1])) # Python 3How it works.
original = [[1, 2], [3, 4]]First the reverse works
>>> original[:Log in to leave an answer
