Title: Understanding Python's range() Function and Working with Variables in a Loop
Introduction:
Python's range() function is a powerful tool for creating sequences of numbers within a specified range. When combined with variables, it becomes a versatile tool for iterating through sequences and performing various operations. This tutorial will guide you through the basics of using variables with the range() function in Python.
The range() function in Python is used to generate a sequence of numbers within a specified range. Its syntax is as follows:
Now, let's explore how to use variables in conjunction with the range() function. We'll create a simple example where a variable is used to control the number of iterations in a loop.

Title: Understanding and Using Variables in Python's range() Function
In Python, the range() function is a powerful tool for creating sequences of numbers. When used in conjunction with variables, it becomes even more versatile. This tutorial aims to explain how to use variables with the range() function in Python, demonstrating the flexibility it brings to your code.
The range() function is used to generate a sequence of numbers. It can take one, two, or three arguments:
Let's explore how to use variables in conjunction with the range() function to create dynamic and reusable code.
In this example, the loop will iterate from 0 to end_value - 1, which is 0 to 4.
This loop will iterate from start_value to end_value - 1, which is 2 to 7.
Here, the loop will iterate from start_value to end_value - 1 with a step of step_value, resulting in 1, 3, 5, 7, and 9 being printed.
This code creates a list containing numbers from start_value to end_value - 1.
Using variables with the range() function allows you to make your code more flexible and maintainable. By adjusting the values of these variables, you can easily change the behavior of your loops without modifying the loop structure itself. This flexibility is crucial for writing clean and adaptable code in Python.
