- Topic: Fast exponentiation in Python. What is Exponentiation? Well, if you want to compute the power of some number in respect to some other number, that is called exponentiation. Now, if we want to compute 2^4 or pow(2,4) , then in general what we will do . Simply, run a loop from 1 to 4 and multiply 2 that no of times. So, below is the approach where we can compute the power value

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])) Share. Improve this answer. edited Apr 2 '20 at 12:13 Python number method exp () returns returns exponential of x: e x I am reading an Intro to Python textbook and came across this line: Operators on the same row have equal precedence and are applied left to right, except for exponentiation, which is applied right to left. I understand most of this, but I do not understand why they say exponentiation is applied right to left. They do not provide any examples either. Also, am I allowed to ask general questions like this, or are only problem solving questions preferred ** Whilst the exponent isn't empty: If the last (smallest) index of the exponent is 1, times result by the base**. Remove the last index of the exponent. Multiply the base by it's self
