A NOR Gate is a logic gate in boolean algebra which results in false0 if any of the inputs is 1, and True1 if all inputs are 0. Following is the truth table of a NOR Gate: Truth Table of NOR Gate:  Input 1   Input 2    Output       0         0         1          0         1         0          1         0         0          1         1         0      Code provided by Akshaj Vishwanathan https:www.geeksforgeeks.orglogicgatesinpython  norgate0, 0 1  norgate0, 1 0  norgate1, 0 0  norgate1, 1 0  norgate0.0, 0.0 1  norgate0, 7 0  printtruthtablenorgate Truth Table of NOR Gate:  Input 1   Input 2    Output       0         0         1          0         1         0          1         0         0          1         1         0       maketablerowOne, Two, Three '   One       Two      Three   '
