You can set a bit in a similar way by shifting 1 left the right number of times. These insights gives you code like this (which reverses x in a field of 'n' bits).

Splunk Team Home react angular Search flipping bits in python Last Update : 2024-08-05 08:41 am WebTo set a specific bit, first, you create a mask by shifting 1 by the specified position, then = (OR equals) the mask with the flag. 04:39 All the bitwise operators support an op-equals variant, meaning you don’t have to write self.door_state = self.door_state . It saves a bit of typing. To close the door, you do something similar.
WebTo toggle a bit, you use the XOR operator. Like with the other methods, create the position bitmask, but this time, ^= (XOR equal) the value. 06:56 Remember that if both bits are on, XOR results in 0. If the door’s closed, the XOR results in 1, meaning open. If the door’s … WebCompute bit-wise inversion, or bit-wise NOT, element-wise.
