Now let’s talk about loops in Python. First we’ll look at two slightly more familiar looping methods and then we’ll look at the idiomatic way to loop in Python. while If we wanted to mimic the behavior of our traditional C-styleforloop in Python, we could use awhileloop: colors=[...
Retry a Loop Action in Python Using thetenacityLibraryretryDecorator Thetenacitylibrary in Python provides a convenientretrydecorator that simplifies the process of retrying a loop action until success. The@retrydecorator enables a function to automatically retry in case of specified exceptions. ...

Similar to if statements, the while loop in Python can also include an else block. The else block is optional and will be executed once if the condition is (or becomes) false. while False: # this code doesn't loop never_runs() else: # instead, this code runs once runs_once() Copy...
Use the while Loop to Loop Over a String in Python A string is a chain of characters, where every character is at a particular index and can be accessed individually. In this tutorial, we loop over a string and print individual characters in Python. Use the for Loop to Loop Over a ...
To print the simple array or numpy array the “print()” method and “for loop” method are used in Python. The “numpy.array()” function creates the numpy array.
While loop favors indefinite iteration, which means we don't specify how many times the loop will run in advance. In Python, a basic while loop looks like this: while [a condition is True]: [do something]Copy The condition we provide to the while statement is the controlling expression, ...
You can also modify the while loop above to output all even numbers between 1 and 10: a =10 b =1 whileb <=10: b+=1 ifb%2==0: print(b) Note:If you don't want to run these examples with Python's built-in IDLE, you canuse Jupyter Notebookas well, but you need tocreate ...
