`for` Loop
Explore how to use for loops in both Python and PowerShell to execute code repeatedly. Understand Python's range function, list iteration, and PowerShell's ForEach and ForEach-Object cmdlets. This lesson helps you grasp loop syntax and practical uses to automate repetitive tasks effectively.
We'll cover the following...
What are loops?
Loops are sets of instructions used to execute a code block repeatedly. Let’s start by discussing the for loop.
for loop
We will often come across scenarios where we will need to repeat or iterate a piece of code over and over without writing the code block multiple times. The for loop is the simplest and most popular type of loop, but there are various ways in which it can be used.
Using the range() method
In Python, for loops can iterate over a number sequence using the range() function. The range function returns a list of numbers within a range that is specified as the function parameter(s).
