How do I use permutations from the itertools module in Python?

You can use the permutations function from the itertools module to generate all possible arrangements of a sequence.

Can you show me a code example?

Sure! Here's a simple example:

import itertools

items = ['A', 'B', 'C']
perms = itertools.permutations(items)
for perm in perms:
    print(perm)

What if I want permutations of a specific length?

You can pass a second argument to permutations, like this:

itertools.permutations(items, 2)
``` This will give you all 2-length permutations.

Are the results sorted?

No, the results are generated in the order of the input sequence. If you need them sorted, you can wrap the result with sorted().
