WebBitmasks can be used to manipulate specific bits in a value. For example, you can force Python to represent the sign of an integer using the left-most bit by manipulating the integer with a bitmask. For example, if you perform the AND operation on an integer and a corresponding bitmask, you get the following [1]: WebSets each bit to 1 if one of two bits is 1 ^ XOR: Sets each bit to 1 if only one of two bits is 1 ~ NOT: Inverts all the bits << Zero fill left shift: Shift left by pushing zeros in from the right …
