Python pow() function

Python pow() function computes the power of a number by raising the first argument to the second argument. This function returns the value of x to the power of y (x^y).

pow(x, y, z) 

• x: It is a number, a base
• y: It is a number, an exponent.
• z (optional): It is a number and the modulus.

Python pow() function example

A simple example code finds the value of a number raised to a certain power.

# returns 2^2
print(pow(2, 3))

# returns -2^3
print(pow(-2, 3))

# returns 1/2^3
print(pow(2, -3))

# returns -1/-2^3
print(pow(-2, -3))

Output:

pow() with Modulus

Let’s calculate the value of 4 to the power of 3, modulus 5 (same as (4 * 4 * 4) % 5):

x = pow(4, 3, 5) 

print(x)
print(type(x))

Output: 4
