When it is required to implement Euler’s number, a method is defined, that computes the factorial.
Another method is defined that find the sum of these factorial numbers.
Below is the demonstration of the same −
Example
def factorial_result(n):
result = 1
for i in range(2, n + 1):
result *= i
return result
def sum_result(n):
s = 0.0
for i in range(1, n + 1):
s += 1.0 / factorial_result(i)
print(s)
my_value = 5
print("The value is :")
print(my_value)
print("The result is :")
sum_result(my_value)Output
The value is : 5 The result is : 1.7166666666666668
Explanation
A method named ‘factorial_result’ is defined, that takes an integer ‘n’ as parameter that computes the factorial of a given number.
Another method named ‘sum_result’ is defined, that takes integer ‘n’ as parameter that iterates over a range of numbers and adds the numbers.
Outside the methods, a value is defined, and the ‘sum_value’ is called by passing this value as parameter.
The output computed is displayed on the console.
