How to invert the elements of a boolean array in Python?

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. 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 ... looks insurance
