Why is this giving no output?

Question

import math

def exp(x):
return sum([
x**n / math.factorial(n)
for n in range(0, 100)
])

exp(1)

Answer 1

i think you need to assign exp() to a varaible and print it. like:

n=exp(1)
print(n)

Answer 2

You don't have to assign anything. Since exp() just returns a value, print that returned value. Last line should be:

print(exp(1))

Answer 3

Tarun Doesn't your code work just fine? Here's the simplified version of your code:

import math

def exp(n):
return sum(x ** n / math.factorial(n) for n in range(100))
