"&" and ".intersection()" difference?

I was wondering whether there is a difference between using "&" and ".intersection()" while finding the intersection of two sets in Python. If so, what are they?

Thank you.

You can read the official documentation. Here is the main difference (emphasis is mine) :

Note, the non-operator versions of union(), intersection(), difference(), and symmetric_difference(), issubset(), and issuperset() methods will accept any iterable as an argument. In contrast, their operator based counterparts require their arguments to be sets. This precludes error-prone constructions like set('abc') & 'cbs' in favor of the more readable set('abc').intersection('cbs').

Using the non operator function does not require to convert the iterable as a set.
