I'm not certain what the goal of the original sentence was, but I think it's
unclear as currently written.
I assume this is what's meant:
my_sequence = [1, 2, 3, 4]
for i, item in zip(count(1), my_sequence):
print(i, item)
This is a strange thing to note though because enumerate would be a better use
here.
my_sequence = [1, 2, 3, 4]
for i, item in enumerate(my_sequence, start=1):
print(i, item)
Maybe what is meant is that count can be used with a step while enumerate
cannot?
my_sequence = [1, 2, 3, 4]
for i, item in zip(count(step=5), my_sequence):
print(i, item)
If that's the case it seems like step should instead be mentioned there instead
of "sequence numbers".
