WebThe Python Tilde Operator ( ~) is a unary operator that performs bitwise inversion. It reverses all the bits in a given number, all ones become zeros and all zeros become ones. The Python Tilde Operator is a unary operator because it takes only one operand (number) and performs an inversion on it. >>> ~0. -1. WebPython Bitwise Operators Example. There are following Bitwise operators supported by Python language. It copies a bit if it exists in either operand. It copies the bit if it is set in one operand but not both. It is unary and has the effect of 'flipping' bits. (~a ) = -61 (means 1100 0011 in 2's complement form due to a signed binary number.

WebDec 17, 2024 · Method 3: We can also use the Tilde operator ( ~) also known as bitwise negation operator in computing to invert the given array. It takes the number n as binary number and “flips” all 0 bits to 1 and 1 to 0 to obtain the complement binary number. So in the boolean array for True or 1 it will result in -2 and for False or 0 it will result ...
