Q. Write a python program to sum the sequence:

1 + 1/1! + 1/2! + 1/3! + …….. + 1/n!

You can understand by Watching video :-

Answer :-

n = int(input("Enter a n = "))
fact = 1
sum = 1
for i in range(1, n + 1):
    fact = fact * i
    sum = sum + 1 / fact
print("Sum of sequence = ", sum)

Output :-

Enter n= 8
Sum of sequence =  2.71827876984127
>>> 

Enter n= 40
Sum of sequence =  2.7182818284590455
>>>
