Finding the number of perfect squares within a given range can be a common task required in various fields such as data analytics, coding challenges, mathematics, and more.
Throughout this tutorial, we will focus on how to accomplish this task using Python, a powerful, flexible, and user-friendly coding language. We will dissect the process step by step to make it easy and understandable, even if you’re a beginner to Python programming.
Step 1: Understanding Perfect Squares
Perfect squares are numbers that have whole numbers as their square roots. They’re the result of squaring whole numbers. For example, the first few perfect squares are 1, 4, 9, 16, 25, and so on.
Step 2: Importing the Necessary Libraries
Before proceeding to the main function, you need to import the math library. This library includes various numerical operations you will need to count perfect squares.import math
Step 3: Defining the Function
The function we’ll define takes in two parameters, ‘start’ and ‘end’. We use the math library’s ‘sqrt’ method and cast it to an integer. Then we will subtract the square root of the start value from the end value. Finally, we need to add 1 to include the end value.

def count_squares(start, end): count = int(math.sqrt(end)) - int(math.sqrt(start)) return count if start > math.pow(int(math.sqrt(start)),2) else count+1 |
The final step is to use our defined function. Simply pass the start number and end number into our function.
|
1 |
print(count_squares(1, 100)) |
The Output
Output: 10
So, within the range of 1 to 100, there are 10 perfect squares.
