Python supports object-oriented programming and has a concise, readable, and easy-to-learn syntax. It is no wonder that it is one of the most popular programming languages. An integral part of Python are its built-in functions.
We've written a series of articles to help you learn and brush up on the most useful Python functions. In this article, we’ll learn about Python's range() function and how to use it.

In this article, we’ll cover:
Python range() function is a built-in function we can use to generate a sequence of numbers within a given range. Through the number of arguments passed to the function, we can control where that sequence of numbers will begin and end, along with the difference between two successive numbers in the series.
Python range() function is often used to iterate through a sequence using a for or while loop.
Python’s range() function takes three arguments:
Please note that:
Returns a sequence of integers with start, stop, and step values as decided by the parameters passed and defaults (for the parameters not provided).
Here, we take a look at how to use the range() function in Python next time you need it:

Q1. What does the range() function in Python generate?
The Python range() function returns a series of integers with the start, stop, and step values as decided by the parameters passed and defaults (for the parameters not provided). The default start value is zero, and the default step value is one.
Q2. What is the default start value in the range() function in Python?
The default value of the start parameter is zero in the range() function in Python.
Q3. What is the default step value in the range() function in Python?
The default value of the step parameter is one in the range() function in Python.
Q4. How do you use the range() function in Python?
The syntax for range() is range(startNumber, stopNumber, stepValue), with startNumber and stepValue being optional parameters.
Q5. Does the end value parameter include itself in the range() function?
No. The range ends at endValue-1 and does not include the endValue itself in the Python range() function.
