With Python, you can use `while` loops to run the same task multiple times and `for` loops to loop once over list data. In this module, you'll learn about the two loop types and when to apply each.
Python, one of the most versatile programming languages, is popular for data science applications, as well as web development, offers various ways to implement loops, particularly the for loop. This explainer will delve into the syntax and functionalities of for loops in Python, providing examples ...

The for loop and while loop are two different approaches to executing the loop statements in python. They both serve the same functionality of looping over a python code till a condition is being fulfilled. For loops and while loops differ in their syntax. In while loops, we have to mention...

So you could use a while loop and a counter to loop or iterate over each item in the list. Because this operation is so common, Python provides for loops, which you can use to iterate over lists.Note Python has many types that can be looped over. These types are known as iterables....

# Python's `for` and `while` loops# support an `else` clause that executes# only if the loops terminates without# hitting a `break` statement.defcontains(haystack,needle):""" Throw a ValueError if `needle` not in `haystack`.
Here, the loop still runs three times because there are three elements in thelanguageslist. Using_indicates that the loop is there for repetition and not for accessing the elements. Nested for loops Aforloop can also have anotherforloop inside it. For each cycle of the outer loop, the inne...
