What are some examples of using itertools in Python?

Itertools is a powerful module in Python for creating iterators for efficient looping. Would you like to see specific examples?

Yes, please provide some examples.

Sure! One common example is using itertools.count() to create an infinite iterator that counts up from a specified number. You can use it like this:

import itertools

for i in itertools.count(10):
    print(i)
    if i >= 15:
        break

That’s great! What about combinations?

You can use itertools.combinations() to generate all possible combinations of a specified length from an iterable. For example:

import itertools

items = ['A', 'B', 'C']
combinations = itertools.combinations(items, 2)
for combo in combinations:
    print(combo)
