Python Program for Sum of series with source code. This python project is useful for beginners and CBSE KV School Class 11 and Class 12 students computer science practical file and NIELIT O Level Programming and Problems Solving through Python (Module M3-R5).
Objective : Write a program to input the value of x and n and print the sum of the following series in Python:
The series are given below :-
Series -1
Screen shot of source code
Explanation of Source Code
x = float (input (“Enter value of x :”)) #float value ae like 4.09
n = int (input (“Enter value of n :”)) #integer value input
s = 0 #s for calculating sum
for a in range (n + 1) : # a loop
s += x**a #sum of series element will be done in this line loop
print (“Sum of series”, s)

Output: Sum of series in python
The output shell python window will be appeared like below:-
Series 2

Explanation of Program
x = float (input (“Enter value of x :”))
n = int (input (“Enter value of n :”))
s = 0
for a in range (n + 1) :
if a%2==0:
s += xa #this caluated sum when the power is even
else: s -= xa # this is calculated when the power is odd
print (“Sum of series”, s) #sum of series element will be done in this line loop
Output : Sum of series
Series 3
Screenshot of source code series 3
Explanation of Python Program
for a in range (n + 1) : #for loop starts
if a%2==0:
s += (xa)/n #odd values are negative even are postive value
else: s -= (xa)/n #sum of series element will be done in this line loop
print (“Sum of series”, s)
x = float (input (“Enter value of x :”))
n = int (input (“Enter value of n :”))
s = 0

Output : Sum of Series Program :-
Series 4
Screenshot of series 4 source code
Explanation of Python Program
x = float (input (“Enter value of x :”))
n = int (input (“Enter value of n :”))
s = 0 #inital value of sum
a=1 #initial value of a
fact=1 #factorial 1
for a in range (1,n + 1) : #for loop starts
fact=fact*a
if a%2==0:
s += (xa)/fact #sum of series element will be done in this line loop
else:
s -= (xa)/fact #sum of series element will be done in this line loop
print (“Sum of series”, s)
