# 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 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

**Getting rid of unwanted characters:**

You can get rid of whitespaces or any specific character using strip methods in Python. You can use either plain strip for both sides, lstrip for the left side and rstrip for the right side only.

str="+++Welcome python+++" str.strip() print(str)

Output:

+++Welcome python+++
