Python Program to Calculate Value Euler's Number (e)

In mathematics, constant e is also known as Euler's number. It is named after the Swiss mathematician Leonhard Euler.

Value of e can be calculated using infinite series. This python program calculates value of Euler's number using series approach.

Python Source Code: Calculation of Euler's Number

# Calculation of Euler Number e
import math

def euler(n):
    t_sum = 0
    for i in range(n):
        term = 1/math.factorial(i)
        t_sum = t_sum + term
    
    return t_sum

# Reading number of terms to be considered in series
terms = int(input("Enter number of terms: "))

# Function call
e = euler(terms)

# Displaying result
print("e = ", e)

Output

Enter number of terms: 1000
e =  2.7182818284590455
