Use thepassstatement if you wantforloops with an empty body, where you wanted to complete the implementation in the future. Empty for is not a valid statement in python hence using will get an error, to avoid this error use a pass statement. If the pass statement is executed, the output...
A loop is a used for iterating over a set of statements repeatedly. In Python we have three types of loopsfor,whileanddo-while. In this guide, we will learnfor loopand the other two loops are covered in the separate tutorials. Syntax of For loop in Python for<variable>in<sequence>:#...
break– Statement is used to exit from the for and while loops. Post exit it executes the immediately following statement of for/while statement it exited from. continue– Skips the current execution and continues with the next iteration of for & while loops. In this article, you will learn ...

Once you learn about for loops in Python, you know that using an index to access items in a sequence isn't very Pythonic. So what do you do when you need that index value? In this tutorial, you'll learn all about Python's built-in enumerate(), where it's used, and how you can...
Typically, you'd either explicitly define a counter variable/index, and manually increment it on each loop, or you'd use some sort of syntactic sugar to avoid this process through enhanced for loops: some_list = ['Looping', 'with', 'counters', 'is', 'a', 'classic!'] # Manual ...
Your implementation of bubble sort consists of two nested for loops in which the algorithm performs n - 1 comparisons, then n - 2 comparisons, and so on until the final comparison is done. This comes at a total of (n - 1) + (n - 2) + (n - 3) + … + 2 + 1 = n(n-1)...
