Python Program to Calculate power using ‘pow()’ method

In this tutorial, we are going to learn a python program to calculate the power of a given number.

pow() Method in python

In Python, the pow() function is used to calculate the power of a number, that is, to raise a number to the exponent of another. It’s a versatile function that can be used in two different ways:

Two Arguments: When pow() is provided with two arguments, it calculates the power of the first argument raised to the second argument. For example, pow(x, y) computes x^y.

result = pow(2, 3)  # Calculates 2^3, which is 8
print(result)  # Output: 8

Three Arguments: The pow() function can also take three arguments. When a third argument is provided, pow(x, y, z), it calculates x^y and then applies modulo z to the result. This is particularly useful for performing modular exponentiation, which is a common operation in fields such as cryptography.

result = pow(2, 3, 3) # Calculates 2^3 = 8, then 8 % 3, which is 2
print(result) # Output: 2

Problem Statement

For any two numbers that are inputs given by the user, one is the base value let’s say it as ‘x’ and the other is the exponent let’s say it as ‘y’, we have to print x^y.

 For example:

Our logic to calculate the power using ‘pow()’ method

• Our program will take two inputs a base number and an exponent number from the user.
• We will ‘pow’ function with arguments as the base number and exponent number.
• Print the output

Python Program to Calculate the power using ‘pow()’ method

#taking 2 integer as input from the user
base = int(input("Enter the value for base :"))
exponent = int(input("Enter the value for exponent :"))
print(base,"to power ",exponent,"=",end = ' ')
print(pow(base,exponent))

Output:

Enter the value for base :5
Enter the value for exponent :4
5 to power  4 = 625

Explanation:

For the input from the user, the base number is 6, and the exponent number is 3. The pow(6, 3) will return 6³ i.e. 216.

The above Python program allows a user to calculate the power of a number by inputting two integers: a base and an exponent. The program starts by asking the user to enter a base number and then an exponent number. It displays these numbers in the format “base to the power of exponent =”. After receiving the inputs, it uses the pow() function to calculate the result of raising the base to the power of the exponent. This result is then printed out directly next to the equal sign and showing the user.
