Python Lists
List is a collection which is ordered and changeable. Allows duplicate members. Tuple is a collection which is ordered and unchangeable. Allows duplicate members. Set is a collection which is unordered, unchangeable*, and unindexed.

5. Data Structures — Python 3.14.3 documentation
We saw that lists and strings have many common properties, such as indexing and slicing operations. They are two examples of sequence data types (see Sequence Types — list, tuple, range). Since Python is an evolving language, other sequence data types may be added.
Python list
Sure. A list is a data type, what is does is stores other types of data in order example = [I’m a string”, 2, 2.45, [“i’am”, “a” “list inside”, “another”], (“tuples”, 2,3), {“set”}, {“my” : “dictionary”}] Types are important to Python, a list is really important to Python because it’s ordered. Each list can be indexed and sliced because they are ordered. print(example[2]) >>>2.45 List start their index at 0 so [2] is the third element. But the last item is… print(example[-1]) >>>{“my”, “dictionary} We can slice them further. print(example[1:4]) #print 2nd to 5th element. >> [2, 2.45, [“i’am”, “a” “list inside”, “another”]] Slicing format example[start:stop:step] and we can go further if we know it’s list and lists, print(example[4][2]) >>>”list inside” Step will skip x amount hint in the list i.e. every 4th element. This can be done negatively as well. And reverse the list. We can loop directly through list… for element in example: if element == 2: break print(“No 2 in the list”) Or check with in if 2 in example: print(“There is a 2”) List can have comprehensions, we loved them so much we made them easier to make list_of_squares = [number**2 for number in range(5)] Lists are great because like all types they have useful methods. Such as, sort(), .append(), .insert(). You can easy check how many elements there are with len(). And since lists in Python can hold anything, anything, you can do a lot of complex requests coming from them. Lists are great for…loops. We want to do the same thing to a bunch of other things.

December 15, 2020Python script for interfaces into a string / list... skip first line?
split_interface_list = interface_list.splitlines()[1:] Above is a simple builtin python list slicing removing the first entry in the list by saying "I want to keep the the 1st element and everything behind it". The 0th element in the list contains the "show int status" and is therefore removed. An alternative way of doing the same thing without the unnecessary "split_interface_list" variable: interface_list = crt.Screen.ReadString(readlines) for interface in interface_list.splitlines()[1:]: print(interface) https://www.geeksforgeeks.org/python-list-slicing/ Edit: got bored so rewrote the script: def main(): '''Checking that terminal is live''' crt.Screen.Synchronous = True crt.Screen.Send("\n") crt.Screen.WaitForString("#") hostname = crt.Screen.Get(crt.Screen.CurrentRow, 0, crt.Screen.CurrentRow, 25).strip() '''Show interface status''' crt.Screen.Send("show interface status | include Eth\n") interface_output = crt.Screen.ReadString(hostname, 5) for interface in interface_output.split("\n")[1:]: try: port, desc, status, vlan, duplex, speed, type = interface.split() crt.Dialog.MessageBox(port) except ValueError: continue main() More on reddit.com

August 20, 2021 - Lists are great to use when you want to work with many related values. They enable you to keep data together that belongs together, condense your code, and perform the same methods and operations on multiple values at once. When thinking about Python lists and other data structures that are types of collections, it is useful to consider all the different collections you have on your computer: your assortment of files, your song playlists, your browser bookmarks, your emails, the collection of videos you can access on a streaming service, and more.

Python Lists: A closer look - by Eric Matthes
January 5, 2023 - It’s sometimes referred to more generally as a collection, but sequence is a better term because a list is an ordered collection. How we name something is important because an accurate name tells us what we can do with that thing. What would you expect to be able to do with a sequence? You’d probably expect to be able to create a sequence, grab items from it, add more items to it, remove some items, change the order of the items, and more. In Python, you can do all of these operations with most sequences, including lists.

Lists are mutable and can include elements of any type, including booleans, integers, strings, dictionaries, or other lists. A Python list is an ordered and changeable (mutable) collection that stores items inside square brackets [], separated by commas.

It slices
x[startAt:endBefore:skip]
if you use skip = 2, every other element the list beginning at startAt and ending at endBefore will be selected. [Remember: indices live BETWEEN list elements]
To see this, enter
x = range(100)
at the Python prompt. Then try these things
x[::2]
x[::3]
x[10:40:6]
and see what happens.

L[x::y] means a slice of L where the x is the index to start from and y is the step size. Here are some examples you can try in the interpreter
>>> L=range(20)
>>> L
[0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19]
If you want every 3rd element
>>> L[::3]
[0, 3, 6, 9, 12, 15, 18]
Now every third element starting from L[1]
>>> L[1::3]
[1, 4, 7, 10, 13, 16, 19]
Now every third element starting from L[2]
>>> L[2::3]
[2, 5, 8, 11, 14, 17]
You can specify a negative step to go backwards
>>> L[::-1]
[19, 18, 17, 16, 15, 14, 13, 12, 11, 10, 9, 8, 7, 6, 5, 4, 3, 2, 1, 0]
You can also assign to this slice, but the value must have the same length as the slice you are replacing
>>> L[::3]=[0,0,0,0,0,0,0]
>>> L
[0, 1, 2, 0, 4, 5, 0, 7, 8, 0, 10, 11, 0, 13, 14, 0, 16, 17, 0, 19]
Finally, you can delete every 3rd element like this
>>> del L[::3]
>>> L
[1, 2, 4, 5, 7, 8, 10, 11, 13, 14, 16, 17, 19]
