Using multiple for loops (one or more) inside a for loop is known as a nested for loop. Here, it prints the elements but skips the print statement and returns to the loop again when it encounters “ mint“.įor clarity, here’s what the output will be: ubuntuĮlementary 6. But, with the continue statement, you will go back to the loop again (continue the loop – literally).įor instance, this is the code: distro = With the break statement, you can stop the loop. Using the continue statement to continue the loop Similarly, you can use the break statement as per your requirement stop the loop anywhere you want. After it prints the second item from the list, it will match the if condition and the break statement will kick in to stop the for loop. So, here, the for loop will print till it encounters mint from the list. Using the break statement to stop the loopĪlong with a for loop, you can specify a condition where the loop stops working using a break statement.įor instance, the code is: distro = Īs you can observe, we have also used the if statement here. With for loop, you can easily print all the letters in a string separately, here’s how to do that: for xyz in "ubuntu": Printing each letter of a string in Python The output to this should look like: ubuntuĮlementary 3. If you want to print the items of the list distro, here’s what you have to write: distro = Suppose you have a list that names some Linux distributions: distro = You can learn more about Indentation in the official Python documentation. For instance, here, the print function belongs inside the for loop and if you add another statement after that without whitespaces, it will be outside the for loop. When you use whitespaces, it will specify the level of the code. You will notice 4 spaces before the print function because Python needs an indentation. Here, numbers is a variable and you can specify any valid variable name. Printing a range of numbers in PythonĪ simple example where you use for loop to print numbers from 0 to 3 is: for numbers in range (4): I shall show you some examples that you can practice for yourself to know more. Now, you are ready to get started learning for loops in Python. Here, the third argument considers the range from 3-10 while incrementing numbers by 2. However, if you want to explicitly specify the increment, you can write: It will consider numbers from 0 to 2 excluding 3 i.e 0,1,2.īy default, the range increments numbers by 1. Suppose, you pass a single argument like range (3). To work with a range of numbers, you might need to use the range() function.įor example, when you write range (3,10), it will consider numbers starting from 3 till 9, excluding 10. It will return true until it finds a value in the sequence, else it will return false. This lets you test a condition of whether something exists (or belongs to) the sequence (list or tuple) that we are working with. You will notice the use of in operator in Python’s for loop when I tell you how to use it in the later section of this article. What Is A Sequence?Ī sequence is essentially a collection of similar objects, it might be a data set, a list of numbers, or a list of strings. You will come across a few things while using the for loop which might be confusing – so, I shall mention a few things before getting started with for loop in Python. A Few Key Points Before You Start Using For Loop If you know any other programming languages, chances are – you already know what it does.Ī for loop in Python is a statement that helps you iterate a list, tuple, string, or any kind of sequence.Įssentially, the for loop is only used over a sequence and its use-cases will vary depending on what you want to achieve in your program. In either case, we shall help you learn more about the ‘ for‘ loop in python using a couple of important examples. Of course, our list of free python resources should help you learn about it quickly. If you are just getting started to learn Python, you must be in search of something to explore for loop in Python.
