Question

I frequently find myself writing code like this:

tupla = (1, 2, 3, 4)
if (1 in tupla) and (4 in tupla):
    ...

Is there any Pythonic way to write this more compactly, without typing tupla twice?

Answer 1

if all(x in tupla for x in list_of_x):

or

if set(list_of_x).issubset(set(tupla)):

The first one will stop as soon as the first x is not in tupla. The second one will create both sets in any case.
