![]() ![]() ![]() Something to note here is that you cannot pass float values to range(). You can pass negative integer values to range() as well: for num in range(-5, 1): If you want a range of values from 5 inclusive to 10 inclusive, you write a range(5,11) like so: for num in range(5,11): Keep in mind that the start value is inclusive, whereas the stop value is not. If you want to have a range of two numbers, you use two arguments – start and stop. How to Use the range() Function with the start And stop Arguments The function started counting from 0, incremented by 1 on each iteration and ended at 4. Let's take a look at the example below: for num in range(5): If you specify a stop argument of 5, the range includes the numbers 0 - 4 and not 0 - 5 – the counting will stop at 4 and not 5. ![]() Keep in mind that the stop value you specify is not inclusive! The counting stops when you reach the value you specify as stop. When using only the stop argument with range(), the counting starts at 0 and increments by 1. How to Use the range() Function with Only the stop Argument This syntax generates a sequence of numbers that starts counting at start (inclusive) and increments according to step until it reaches stop (non-inclusive). The syntax to do that looks like this: range(start, stop, step) Lastly, if you don't want the default increment to be 1, you can specify a third optional argument, step. This syntax generates a sequence of numbers based on the start (inclusive) and stop (non-inclusive) values that increment by 1. The syntax to do so looks like this: range(start, stop) You can pass a second optional start argument, start, to specify the starting number. The range() function returns a sequence of numbers starting from 0, incrementing by 1, and ending at the value you specify as stop (non-inclusive).īut what if you want to iterate through a range of two numbers you specify and don't want to start the counting from 0? The range() function accepts three arguments – one is required, and two are optional.īy default, the syntax for the range() function looks similar to the following: range(stop) Python's built-in range() function is mainly used when working with for loops – you can use it to loop through certain blocks of code a specified number of times. What is the range() Function in Python? range() Function Syntax Breakdown In this article, you will learn how to use the range() function in Python with the help of code examples along the way. ![]()
