How to calculate the exponential value in Python? : Pythoneo

Let’s learn How to calculate the exponential value in Python.

Using an asterisk

The easiest way to calculate the exponential value in Python is to use the exponentiation operator (**) double asterisk.

my_base = 5
my_exponent = 3
print ("Exponential value equals: ", my_base ** my_exponent)

my_base = 5
my_exponent = -3
print ("Exponential value equals: ", my_base ** my_exponent)

my_base = -5
my_exponent = 3
print ("Exponential value equals: ", my_base ** my_exponent)

my_base = -5
my_exponent = -3
print ("Exponential value equals: ", my_base ** my_exponent)

Using a pow method

You can also write in the different way by using the pow function of math module.

import math

my_base = 5
my_exponent = 3
print ("Exponential value equals: ", math.pow(my_base, my_exponent))

my_base = 5
my_exponent = -3
print ("Exponential value equals: ", math.pow(my_base, my_exponent))

my_base = -5
my_exponent = 3
print ("Exponential value equals: ", math.pow(my_base, my_exponent))

my_base = -5
my_exponent = -3
print ("Exponential value equals: ", math.pow(my_base, my_exponent))

Using an exp method

In case you would like to calculate the exponential value of Euler’s constant number you need to use exp method of math module.

import math

my_exponent = 3
print ("Exponential value equals: ", math.exp(my_exponent))
