How do I do exponentiation in python?

def cube(number):
  return number^3
print cube(2)

I would expect cube(2) = 8, but instead I’m getting cube(2) = 1

What am I doing wrong?

Method 1

^ is the xor operator.

** is exponentiation.

2**3 = 8

Method 2

You can also use the math library. For example:

import math
x = math.pow(2,3) # x = 2 to the power of 3

Method 3

if you want to repeat it multiple times – you should consider using numpy:

import numpy as np

def cube(number):
    # can be also called with a list
    return np.power(number, 3)

print(cube(2))
print(cube([2, 8]))
