This is one case of chained comparisons: http://docs.python.org/3/reference/expressions.html#not-in "x <= y <= z" is equivalent to "(x <= y) and (y <= z)" "x in y == z" is equivalent to "(x in y) and (y == z)" There is a jump if the 'in' expression is false, because 'and' should short-circuit the second comparison.

This is one case of chained comparisons:

"x <= y <= z" is equivalent to "(x <= y) and (y <= z)"
"x in y == z" is equivalent to "(x in y) and (y == z)"

There is a jump if the 'in' expression is false, because 'and' should short-circuit the second comparison.
