Python Math: Calculate the difference between the squared sum and the sum of squared of first n natural numbers
Python Math: Exercise-11 with Solution
Write a Python program to calculate the difference between the squared sum of the first n natural numbers and the sum of squared first n natural numbers.(default value of number=2).
Sample Solution:-
Python Code:
def sum_difference(n=2):
sum_of_squares = 0
square_of_sum = 0
for num in range(1, n+1):
sum_of_squares += num * num
square_of_sum += num
square_of_sum = square_of_sum ** 2
return square_of_sum - sum_of_squares
print(sum_difference(12))
Sample Output:
5434

Combining Lists Using Zip:
- Takes multiple collections and returns a new collection.
- The new collection contains items where each item contains one element from each input collection.
- It allows us to transverse multiple collections at the same time.
name = 'abcdef' suffix = [1,2,3,4,5,6] zip(name, suffix) --> returns (a,1),(b,2),(c,3),(d,4),(e,5),(f,6)
