Python code to find power of a number using loopnum = int(input("Enter the number of which you have to find power: ")) pw = int(input("Enter the power: ")) kj = 1 for n in range(pw): kj = kj*num print(kj) Output
To calculate the power of a number, the “math.pow()” function is utilized in the Python program. It returns a value of base raised to a power of exponent. The “math.pow()” function takes two parameter values, base and exponent. The function returns “ValueErrors” when the base nu...
