Python Exercises for Beginners #28 | for loop example: Squares of numbers 1 to 5 | Python Tutorial
Welcome to @yasirbhutta ! In this quick Python tutorial, we’ll show you how to write a simple `for` loop to print the squares of numbers from 1 to 5. Perfect for beginners, this video walks you through setting up the loop using the `range` function and explains how to calculate the square of each number using the `**` operator.
🔍 *What You'll Learn:*
How to use the `range` function in Python.
Writing a basic `for` loop to iterate through numbers.
How to calculate and print squares of numbers in Python.
👨💻 *Code Featured in This Video:*
```python
for i in range(1, 6):
print(i**2)
```
1. **`for i in range(1, 6):`**: This line creates a loop that iterates over a sequence of numbers. `range(1, 6)` generates a sequence of numbers starting from 1 up to, but not including, 6. So it will generate the numbers 1, 2, 3, 4, and 5.
2. **`print(i**2)`**: Inside the loop, this line prints the square of the current number (`i`). The `**` operator is used for exponentiation, so `i**2` calculates the square of `i`.
As a result, the code prints the squares of the numbers from 1 to 5:
For `i = 1`, it prints `1**2` which is `1`.
For `i = 2`, it prints `2**2` which is `4`.
For `i = 3`, it prints `3**2` which is `9`.
For `i = 4`, it prints `4**2` which is `16`.
For `i = 5`, it prints `5**2` which is `25`.
So the output will be:
```
1
4
9
16
25
```
