Solution of Exercise 211: setof perfect square in python

Exercise 211

Write a Python program that returns the set of perfect square integers less than or equal to 100.

Solution

# function that tests if a number is a perfect square
def perfectSquare(n):
    test=False
    for i in range(0 , n+1):
        # test if n is perfect square and change test to True
        if i**2 == n:
            test=True
    return test

# initialization of the requested set
A = set({})

# iterate over integers from 1 to 100
for i in range(0, 101):
    # test if 'i' is a perfect square
    if perfectSquare(i):
        A.add(i)

# display the set of perfect squares
print("A = ", A)
# output: A = {0, 1, 64, 4, 36, 100, 9, 16, 49, 81, 25}
