Q N : 9 : Write a Python program that takes list of numbers as input from the user and produces a cumulative list where each element in the list at any position n is sum of all elements at positions upto n-1.

Answer No : 9 :

nl=[]
L=[10,20,30,40,50]
l=len(L)
nl.append(L[0])
for x in range(1,l,1):
    s=nl[x-1]+L[x]
    nl.append(s)
print(nl)
