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.

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...

Reduces the code’s complexity: Loop repeats a specific block of code a fixed number of times. It reduces the repetition of lines of code, thus reducing the complexity of the code. Usingforloops andwhileloops we can automate and repeat tasks in an efficient manner. ...

while loops are commonly used to iterate an unknown number of times, which is useful when the number of iterations depends on a given condition.Python has both of these loops and in this tutorial, you’ll learn about for loops. In Python, you’ll generally use for loops when you need to...
