How can I print infinity loop using for loop? [Phyton]

Answer 1

1. You can loop infinitely through a finite iterable, using itertools.cycle

2. You can write a custom infinite generator (using a while loop) then iterate through it with for loop.

3. Just use a while loop :)

Answer 2

MD. Ferdous Ibne Abu Bakar ,

if you don't need to get any value from the loop, we can use:

from itertools import repeat
for _ in repeat(None):
# ... your code to perform

if you need a value we can use itertools count() instead, which returns numbers

Answer 3

A͢J ,

just to mention that using a 'dummy'-list and append items to simulate an infinite loop is acceptable for only a few iteration steps. but as soon as we iterate sequences with a great number of items, the 'dummy'-list will grow and the same is with the memory consumption.

You can also take empty list and append item in that list:

l = [0]

for _ in l:
print (len(l))
l.append(_)
