How do I install itertools in Python?

You don't need to install itertools separately; it's included in Python's standard library. You can use it directly.

Can you show me an example of how to use itertools?

Sure! Here's a simple example using itertools to create a Cartesian product:

import itertools
result = list(itertools.product([1, 2], ['a', 'b']))
print(result)  # Output: [(1, 'a'), (1, 'b'), (2, 'a'), (2, 'b')]

What other functions does itertools provide?

itertools provides many functions like count, cycle, repeat, combinations, permutations, and more for efficient looping.

Is itertools available in Python 2?

Yes, itertools is available in both Python 2 and Python 3. However, some functions may differ slightly.
