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.
8 wrz 2008 · I take advantage of Bash's brace expansion to create for loops that allow me to create non-numerical for loops. Example: I want to run the uptime command on frontend hosts 1-5 and backend hosts 1-3: % for host in {frontend{1..5},backend{1..3}}.mycompany.com do ssh $host "echo -n $host; uptime" done
In this introductory tutorial, you'll learn all about how to perform definite iteration with Python for loops. You’ll see how other programming languages implement definite iteration, learn about iterables and iterators, and tie it all together to learn about Python’s for loop.
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 Python, we use a for loop to iterate over various sequences, such as lists, tuples, sets, strings, or dictionaries. The for loop allows you to iterate through each element of a sequence and perform certain operations on it.
