And, If I want to do a for …

Using the same iterator in nested for loops Question: Consider the following code: from itertools import chain lst = [‘a’, 1, 2, 3, ‘b’, 4, 5, ‘c’, 6] def nestedForLoops(): it = iter(lst) for item0 in it: if isinstance(item0, str): print(item0) else: # this shouldn’t happen because of # 1. lst[0] is a str, and …
Nested loop provides unwanted action Question: I am trying make a nested loop so a while loop gets repeated n times. An object is supposed to drive a distance in i steps for n repetitions. Axis and speed are irrelevant for the loop. What I don’t understand is why the first i in i = …
