Python Program to Find Sum of Series 1/1! 2/2! 3/3! …1/n!

• Python Program to Find Sum of Series 1/1! 2/2! 3/3! …1/n! using for loop
• Python Program to Find Sum of Series 1/1! 2/2! 3/3! …1/n! Using Function

Python Program to Find Sum of Series 1/1! 2/2! 3/3! …1/n! using for loop

Use the following steps and write a python program to find sum of the series 1/1! + 2/2! + 3/3! + ……1/n! using for loop:

• Take the input number of the term to the user.
• Initialize the sum1 name variable to 0.
• Use a for loop to iterate from 1 to the user given term number with find the sum of the series.
• Print the sum of the series.

n=int(input("Enter the number of terms: "))
sum1=0
for i in range(1,n+1):
    sum1=sum1+(1/i)
print("The sum of series is",round(sum1,2))

Output

Enter the number of terms:  5
The sum of series is 2.28

Python Program to Find Sum of Series 1/1! 2/2! 3/3! …1/n! Using Function

Use the following steps and write python program to find sum of the series 1/1! + 2/2! + 3/3! + ……1/n! using function:

• Take the input number of the term to the user.

#Python Program to Find Sum of Series 1/1!   2/2!   3/3!   …1/n! using function

#define a function
def sumOfSeries(num): 
      
    # Computing MAX 
    res = 0
    fact = 1
      
    for i in range(1, num+1): 
        fact *= i 
        res = res + (i/ fact) 
          
    return res 
      
  
n=int(input("Enter the number of terms: "))

print("Sum: ", sumOfSeries(n)) 

Enter the number of terms:  5
Sum:  2.708333333333333
