Comparing two lists with specific values to read
I have two lists and when I loop through the list and I managed to get the difference, but I need time as well because it is a separate item and ‘uvz’ does not mean to me anything in the list with a few thousand entries. I tried to convert it to the dictionary, but it overwrites with the last

Pythonic method to create 2 lists, one of which is a repeating set of strings and turn into a dict
I have a list of ‘widget types’, [“C”,”A”,”B”] and need to make a dict for those types to correspond to their respective ID’s, 1=’C’, 2=’A’, 3 = ‘B’, 4= ‘C’, 5=’A’, 6= ‘B’, 7 = ‘C’, etc. I already know how to do it, I just wondered if there was a more elegant pythonic way of achieving it than that
Python – Iterating through 2 list with arithmetic function
I have 2 python list, stock_level to track the amount of inventory and required to indicate the amount of each item in stock_level needed to create each product.

Fastest way to split a list into a list of lists based on another list of lists
Say I have a list that contains 5 unique integers in the range of 0 to 9. I also have a list of lists, which is obtained by splitting integers from 0 to 19 into 6 groups: Now I want to split lst based on the reference partitions. For example, if I have I expect the output to be a
Is there a better way to find specific value in a python dictionary like in list?
I have been practicing on iterating through dictionary and list in Python. The source file is a csv document containing Country and Capital. It seems I had to go through 2 for loops for country_dict in order to produce the same print result for country_list and capital_list. Is there a better way to do this in Python dictionary? The code:
