Day 15 : Python Program to find all perfect squares in a given range

 

def perfect_squares(start, end):

    squares = []

    for num in range(start, end + 1):

        if (num ** 0.5).is_integer():  

            squares.append(num)

    return squares

start = int(input("Enter the start of the range: "))

end = int(input("Enter the end of the range: "))

print(perfect_squares(start, end))

Code Explanation:

1. Defining the Function

def perfect_squares(start, end):

def: This keyword is used to define a new function in Python.

perfect_squares: The name of the function, which suggests its purpose (to find perfect squares).

start, end: These are the input arguments (parameters). start is the lower bound of the range, and end is the upper bound.

2. Initializing an Empty List

    squares = []

squares: This is an empty list that will store all the perfect squares found within the given range.

3. Iterating Through the Range

    for num in range(start, end + 1):

for num in range(start, end + 1):

A for loop that iterates over each number from start to end (inclusive).

range(start, end + 1): Generates a sequence of numbers starting at start and ending at end.

4. Checking for Perfect Squares

        if (num ** 0.5).is_integer():

num ** 0.5: Calculates the square root of the current number (num).

.is_integer(): Checks if the square root is an integer.

If the square root is a whole number, it means num is a perfect square.

5. Adding Perfect Squares to the List

            squares.append(num)

squares.append(num): Adds the current number (num) to the squares list if it passes the perfect square check.

6. Returning the List

    return squares

return squares: After the loop finishes, the function returns the list of all perfect squares found within the range.

7. Taking User Input for the Range

start = int(input("Enter the start of the range: "))

end = int(input("Enter the end of the range: "))

input(): Displays a prompt to the user and reads their input as a string.

int(): Converts the user input from a string to an integer.

The user is asked to provide the starting (start) and ending (end) numbers for the range.

8. Calling the Function and Printing the Result

print(perfect_squares(start, end))

perfect_squares(start, end): Calls the function with the user-provided range.

print(): Displays the resulting list of perfect squares.
