Question
1. Give the Python program that computes the square of a number. The number is passed to the function as a parameter. The output is the square of this number. For example, the function can be used as shown below
. . . .
n = s q u a r e ( 7 )
. . .
2. Another very useful feature of Python is looping, which is more flexible than that available in BB.
For example:
while i <10:
p r i n t ( i )
will give the following output:
0
1
2
3
4
5
6
7
8
9
In this experiment, give the Python program that outputs the sum of squares of numbers from 1 to n, i.e. y = 12 + 22 + 32 + ... + n2
where n is specified by the user at run time.
Hints:
• y can be computed using a loop, say, while.
• Before you can use the while loop, you need to initialize y with 0.
• In the ith iteration of the loop, add i2 to y, i.e. y = y + i2 .
Explanation / Answer
1) Python code to find out the square of number is given below:
def square(value):
return value*value
n = square(7)
print(n)
2)Python code for finding out the sum of square of n numbers
def sumOfSquare(value):
sum = 0
i = 1
j = int(value)
while (i<=j):
sum = sum + i*i
i = i+1
return sum
n = input('Enter the value of n: ')
squareSum = sumOfSquare(n)
print(squareSum)
