lists | Utilities for go slices and maps | Map library

Assume I have a class with three lists as follows:

How do I check user input against multiple lists python?

Ex. I want to check if an input is in one of four lists. One list for up down left and right. Each list has the different acceptable ways to make the program continue. Once the input is verified to be in one of the lists i will need to figure out how to make it check against the individual lists so that the input correlates correctly to the desired direction.

Custom characters are used in two spots but they print properly.

Current Code:

I'm trying to add lists together using a loop. Here is some example data.

I have a simple code where I try to define a vector as one of two initializer lists using a ternary operator:

My app consists in letting you add lists in which you can keep your notes. Therefore, I have this NotesListActivity where I can add and keep my Lists. I wanted to filter this lists following the https://www.youtube.com/watch?v=CTvzoVtKoJ8 tutorial and then I tried to adapt it to my code like below. Could you please tell me what is the problem here, cause I don't even get an error, I just not get any title of list as result. So, this is what I have in my RecyclerAdapter:

I have to parse lists of names, addresses, etc. that were OCRed and have invalid/incorrect characters in them and on the state postal code I need to recognize the pattern with a 2 character state followed by a 5 digit postal code and replace any non numeric characters in the postal code. I might have OK 7-41.03 at the end of a string I need to remove the hyphen and period. I know that re.sub('[^0-9]+', '', '7-41.03') will remove the desired characters but I need it only replace characters in numbers when found at the end of the string and only if preceded by a two character state wrapped in spaces like OK. It seems if I add anything to the regular expression as far as a lookbehind expression then I can't seem to get the characters replaced. I've come up with the following but I think there must be a simpler expression to accomplish this. Example:

I am writing a program in python to have a user input multiple websites then request and scrape those websites for their titles and output it. However, when the program surpasses 8 websites the program crashes every time. I am not sure if it is a memory problem, but I have been looking all over and can't find any one who has had the same problem. The code is below (I added 9 lists so all you have to do is copy and paste the code to see the issue).

When I use the following code to print all subsets of the string "abc", the code works as expected, printing : ab a b

So let us say that we have a 2 dimensional list of numbers:
