What are some basic examples of using itertools in Python?

Can you give me some basic examples of using itertools in Python?

Sure! The itertools module provides various functions that work on iterators to produce complex iterators. For example, itertools.count() generates an infinite sequence of numbers.

Can you show me how to use itertools.product?

Absolutely! itertools.product computes the Cartesian product of input iterables. For instance, itertools.product([1, 2], ['a', 'b']) will yield (1, 'a'), (1, 'b'), (2, 'a'), (2, 'b').

What about itertools.combinations?

itertools.combinations returns all possible combinations of a specified length from the input iterable. For example, itertools.combinations([1, 2, 3], 2) gives you (1, 2), (1, 3), and (2, 3).

Can you explain itertools.permutations?

Sure! itertools.permutations returns all possible arrangements of the input iterable. For example, itertools.permutations([1, 2, 3]) will yield (1, 2, 3), (1, 3, 2), (2, 1, 3), and so on.
