Program of Cumulative sum in python

What is the cumulative sum?

The cumulative sum means “how much so far”. The definition of the cumulative sum is the sum of a given sequence that is increasing or getting bigger with more additions. The real example of a cumulative sum is the increasing amount of water in a swing pool.

Example:

<br />
Input: 10, 15, 20, 25, 30<br />
Output: 10, 25, 45, 70, 100</p>
<p>Input: 1, 2, 3, 4, 5 6, 7 ,8, 9, 10<br />Output: 1, 3, 6, 10, 15, 21, 28, 36, 45, 55<br />

Program: 1

<br /># Cumulative sum<br />def Cumulative_sum(lists):<br />	cum_list = []<br />	length = len(lists)<br />	cum_list = [sum(lists[0:x:1]) for x in range(0, length+1)]<br />	return cum_list[1:]</p>
<p>lists = [10, 15, 20, 25, 30]<br />print (Cumulative_sum(lists))<br />

Output:

10, 25, 45, 70, 100

Program: 2

<br />
list=[1, 2, 3, 4, 5, 6, 7, 8, 9, 10]<br />
cum_list=[]<br />
y = 0<br />
for x in range(0,len(list)):<br />
y+=list[x]<br />
cum_list.append(y) </p>
<p>print(cum_list)<br />

Output:

1, 3, 6, 10, 15, 21, 28, 36, 45, 55

Program 3: User define program

<br />
i = []<br />
n = int(input(“enter the no of elements in list:”))<br />
for x in range(0,n):<br />
element=int(input(“enter the element” + str(x+1) + “:”))<br />
i.append(element)<br />
j=[sum(i[0:x+1]) for x in range(0,len(i))]<br />
print(“Original list is: “,i)<br />
print(“Cumulative sum list is: “,j)<br />

Output:

enter the no of elements in list: 10
enter the element1: 2
enter the element2: 3
enter the element3: 8
enter the element4: 6
enter the element5: 45
enter the element6: 32
enter the element7: 56
enter the element8: 32
enter the element9: 14
enter the element10: 25
Original list is: [2, 3, 8, 6, 45, 32, 56, 32, 14, 25]
Cumulative sum list is: [2, 5, 13, 19, 64, 96, 152, 184, 198, 223]
