python convert a binary number to a decimal number
def binToDec(num): temp = str(num) arr = [] final = [] for i in temp: arr.append(i) arrNums = [str(x) for x in arr] arrNums.reverse() j = 0 for i in range(0, len(arrNums)): factor = arrNums[i]*(2**j) j += 1 final.append(factor) decimal = 0 for i in range(0, len(final)): decimal += final[i] return decimal if __name__ == "__main__": num = 101000 print(binToDec(num)) # Expected Output : 40
