usin "in" list

Question

ages = [11,23,44,46,67]
print(11 in ages) = true
print(2 and 11 in ages) = true
print(11 and 2 in ages) = false
print((2 and 11) in ages) = true
print((11 and 2) in ages) = false

can anyone please explain reason for above output.

Answer 1

2 is true
11 in ages is true

11 is true
2 in ages is false

it is different to
2 in ages and 11 in ages

Answer 2

2 and 11 in ages doesn't mean what you think it means.

It checks if 2 is true (which it is), and then it checks if 11 is in ages.

So you need to write:

2 in ages and 11 in ages
