Exponents are mathematical operations that represent the number of times a number (the base) is multiplied by itself. This short and straight-to-the-point article shows you 2 different approaches to calculating exponents in Python. Without any further ado, let’s get our hands dirty with code.
Using the ** operator
Like many other programming languages, Python uses the
** operator for exponentiation. The example below shows you how to use the
** operator to calculate the result of 10 to the power of 3:
output = 10 ** 5 print(output)
10 is the base, and
5 is the exponent.
Here’s another example with the exponent is a float:
result = 10 ** 3.25 print(result)
Using the math.pow() function
** operator, you can use the
pow() function of the
math module to get the job done.
import math result1 = math.pow(2, 4) result2 = math.pow(2, 1.5) print('result1 =', result1) print('result2 =', result2)
result1 = 16.0 result2 = 2.8284271247461903
Note that the
pow() function always returns a float. In the example above, you get
16.0 instead of
