30 paź 2023 · for Loops Using Associative Arrays. Iterating Over the output of Commands. The Dazzling for Loop. The versatile Bash for loop does much more than loop around a set number of times. We describe its many variants so you can use them successfully in your own Linux scripts.
In this tutorial, we are going to learn about for loop in Python. We will see how to use it in different ways, iteration over numbers, list, dictionary, tuple, string, range, set, file, etc with multiple examples.
15 wrz 2023 · Simple For loop. To execute a for loop we can write the following syntax: #!/bin/bash. for n in a b c; do. echo $n. done. In the first iteration, n takes the value “a”, and the script prints “a”. In the second iteration, n takes the value “b”, and the script prints “b”.

Python For Loops. A for loop is used for iterating over a sequence (that is either a list, a tuple, a dictionary, a set, or a string). This is less like the for keyword in other programming languages, and works more like an iterator method as found in other object-orientated programming languages.
To declare a for loop in bash, we can declare either an index-based for loop or a range-based for-loop. To declare an index based for-loop, we will use the following syntax:
