Dear all,
I sometimes want to use an infinite while loop with access to the
loop
index, like this:
def naturals():
i = 0
while True:
yield i
y += 1
for i in naturals():
print(i)
I assume a function like 'naturals' already exists, or a similar
construction for the same purpose. But what is it called?
for i, item in enumerate(iterable):
....
This only moves the problem to the variable 'iterable'. And moreover
is more complex than needed; it give '(i, item)', whereas I only need
the index 'i'.
