A for loop implements the repeated execution of code based on a loop counter or the loop variable. For loops are used when the number of iterations is known in advance. This is the structure of a basic for loop in Python: for[Temporary variable]in[sequence]: [do something] ...
To understand how to loop without aforloop, we’ll need to discover what makesforloops tick. We’re about to learn howforloops work in Python. Along the way we’ll need to learn about iterables, iterators, and the iterator protocol. Let’s loop. ➿ Looping with indexes: a failed at...

In the Robot Framework, we can use for loops with lists using the built-in FOR loop construct in combination with Python code. Here’s an example of how to do this: Define your list in a test case or keyword: *** Test Cases *** Example Test Case ${my_list}= Create List item1...
for-in: the usual way What if we need indexes? range of length enumerate What if we need to loop over multiple things? enumerate zip Looping cheat sheet In Summary Practice makes perfect For loops in other languages Before we look at Python’s loops, let’s take a look at a for loop...
This article covers the construction and usage of While loops in Python. While Loop In Python A while statement iterates a block of code till the controlling expression evaluates to True. While loop favors indefinite iteration, which means we don't specify how many times the loop will run in...
However, there are scenarios where you need more control over the flow of your loops. For instance, you might encounter a situation where you need to exit a loop prematurely, skip the current iteration, or simply have a placeholder for future code. Python provides three powerful statements to...
In Python,whileloops are constructed like so: while[a conditionisTrue]:[do something] Copy The something that is being done will continue to be executed until the condition that is being assessed is no longer true. Let’s create a small program that executes awhileloop. In this program, ...
You already used one of them, the Python interactive interpreter, also known as the read-evaluate-print loop (REPL). Even though the REPL is quite useful for trying out small pieces of code and experimenting, you can’t save your code for later use. To save and reuse your code, you ...
For an overview of iterators in Python, take a look at Python “for” Loops (Definite Iteration). Now that you have a rough idea of what a generator does, you might wonder what they look like in action. Let’s take a look at two examples. In the first, you’ll see how generators...
