1.	Write Python script to calculate sum of following series :s = (1) + (1+2) + (1+2+3) +…+ (1+2+3+…+n)
Answer» sum 0 n = int (raw_input (“Enter the value of n :”)] for a in range (2, n+2): term = 0 for b in range (1,1): term + = b print “Term”, (a-1), “:”,term sum + = term print “Sum of”, n, “term is”, sum

Write Python script to calculate sum of following series :s = (1) + (1+2) + (1+2+3) +…+ (1+2+3+…+n)

Answer»

sum 0

n = int (raw_input (“Enter the value of n :”)]

for a in range (2, n+2):

term = 0

for b in range (1,1):

term + = b

print “Term”, (a-1), “:”,term

sum + = term

print “Sum of”, n, “term is”, sum
