Small integer caching: https://wsvincent.com/python-wat-integer-cache/ https://wsvincent.com/python-wat-integer-cache/ The objects for small integers are built-in and static, but 17^2 is too big, and so new integer objects are created when the expressions are evaluated. "is" checks if two expressions represent the same object in memory. "==" checks for equality of values.
