Is there a difference between 'and' and '&' with respect to python sets?

Question

I got very good help for question check if dictionary key has empty value . But I was wondering if there is a difference between and and & in p

Answer 1

Yes and is a logical and whereas & is a bitwise and. See example -

>>> 1 and 2
2
>>> 1 & 2
0

The first result is due to short circuiting. Python tests 1 and finds it true and returns the 2. But, the second part does 01 (Binary 1) & 10 (Binary 2) hence evaluating to 00 (1 & 0, 0 &1) , which is 0.
