What does 'execution timed out' means in Python how is it caused and how to avoid it?

Question

lst = eval(input("enter elements "))
count = 0
for item in lst:
num = item
sum = 0
while item > 0:
dg = item % 10
sum += dg**3
item //= item
if sum == num:
count += 1
print(count)

This is the code that I've written it only takes the input and doesn't print anything while using an IDE while running it on sololearn shows an ' execution timed out ' can anybody tell me what's happening?

Edit: o.gak thanks and sorry for the dumb mistake.
Ipang thank you, I will try to be more relevant next time.

Answer 1

You got an infinite loop, because of
'item //= item'.
'item' will always be 1 in your code.
