I find it's a valid expression: `1 in [1, 2, 3] in [4, 5, 6]` `a in b in c` is equivalent to `a in b and b in c` but this expression seems useless, and easy to confused with (a in b) in c . in this program, what I originally want is `if a in b and a in c` , But it was mistakenly written as `a in b in c` This expression is similar to `a<b<c` 。 But it seems very unreasonable here, is this a bug ?
