Extending List Function With Range Function
In the previous Python tutorial, we learned about the list built-in function in this tutorial we are going to look at extending the list function with range function. List function converts our provided argument into a list object using the range function with the list function not only speeds up writing numbers that are in a sequence but make it a whole lot easier.

For example, say we needed a list of numbers between 0 and 20 for our program it would be easier to write using the list function with range function being the argument. Using the range function on list function, we would be returned a list that contained the numbers 0 thru 20.

List Function With Range Function Syntax
list(range(start, stop, step))

list() - The list function converts our argument into a list object.
range() - The range function will provide us with a sequence of numbers.
start - This is the starting argument. Whichever number we provide here is where the range function will start listing its numbers in a sequence.
stop -This is the stopping argument. This argument shows where we would like our range to stop. For example, if we provide 10 as our stopping number the list will actually stop on 9. This is like slicing the stop number always ends one number before you indicate.
step - This is the stepping argument. Which will skip the number by the number provided.
Examples Of The List Function with Range Function
Example With Stop Argument
list(range(4))
[0, 1, 2, 3]
Example Explained

list(range(4)) - We create a list function that takes the range function as an argument. We provide one argument to the range function. When we provide one argument to the range function the list will count up from zero to the number we include in the range function. In this case, we provide the number four as an argument so we will get a list from 0 to 4.

[0, 1, 2, 3] - We are returned a list object that contains the numbers 0 thru 3.

Example With Start and Stop Argument
list(range(0, 5))
[0, 1, 2, 3, 4]
Example Explained

list(range(0, 5)) - In this example we include a starting point and ending point for range.

[0, 1, 2, 3, 4] - We are returned a range numbers from 0 and 4.

Example With Stepping
list(range(0, 11, 2))
[0, 2, 4, 6, 8, 10]
list(range(0, 11, 2)) - In this example we call range as an argument on the list function and provide a stepping argument. The stepping argument indicates how many numbers do we want to count by.

[0, 2, 4, 6, 8, 10] - We are returned a list of numbers that count by 2.
