I started writing a small CLI menu library in python. I'm uncertain of the structure and scalability of the current code. For example the Menu.choice method would grow very large if were to add more options for navigation input. Could this be better done with a class to handle the input?

Given a string in a 24 hour format the program outputs a 12 hour format. The rules are:
The output format must be 'hh:mm a.m.' if it represnt before midday and 'hh:mm p.m.' after midday
When the hour is less than 10:00 you should not write a 0 before the hour, example: '9.05 a.m.'

Just edited a question mistagged as VBA to instead use a new visual-foxpro tag.
After looking at tag synonyms for VBA, I see there is no visual-basic-applications tag, so perhaps the new tag I created should instead be vfp if abbreviations are preferred?

array = [10,5,2,7,8,7,9]
k = 3
for index in range (len(array)-2):
print(max(array[index:index+3]))
The challenge
Given an array of integers and a number k, where 1 <= k <= length of the array, compute the maximum values of each subarray of length k.
For example, given array = [10, 5, 2, ...
This is the problem:
Write a function to create a table from CSV data.
The input to the function is a list of strings. Each string is formatted as a CSV record. Here’s an example for a possible input:

Enums with the FlagsAttribute have the disadvantage that you need to be careful when assigning their values. They are also inconvenient when you would like to allow the user of the library to add their own options. The enum is closed/final.
My alternative Option class should solve these two issu...
I implemented a tree search with javascript.

A(1) …, A(n) with the minimum number of scalar multiplications.
Thus, we have to f...

Given a list of unique words, find all pairs of distinct indices (i,
j) in the given list, so that the concatenation of the two words, i.e.
words[i] + words[j] is a palindrome.
