I’ve tried to find this specific question answered but not had any luck. Suppose I have a pandas dataframe with the following columns: A B C 1 2 3 4 5 6 All I’m trying to achieve is a new dataframe that has all combinations of the unique values in the individual columns themselves, so:… Read More Combinations of all possible values from single columns

I am trying to give the unique permutations of a set, a.k.a the combinations of a set. For example, the combinations of the set S={A,B,C} are: SC={AB, AC, BC} BA isn’t valid as AB=BA, for example. I tried using tools like the cartesian product but I realized that would be for two sets. I could… Read More Combinations of a set in Java

I have three lists: list_a=[1,2] list_b=[3,4] list_c=[5,6] Now i’m looking for a solution in python by using a loop where a new list iterates through all possible combinations of these three lists (the order is not important): new_list = list_a # -> [1,2] new_list = list_b # -> [3,4] new_list = list_c # -> [5,6]… Read More How to get all possible combinations of three lists

I have a pandas dataframe in python, with the following structure: Date A B C D E F G H 2022-01-01 10:00:00 1 3 0 4 1 0 0 1 2022-01-01 11:00:00 0 1 1 2 0 2 3 5 2022-01-01 12:00:00 0 2 0 1 0 1 0 0 2022-01-01 13:00:00 0 0 2… Read More Possible combinations of pandas columns from a list

I can generate combinations from a list of numbers using itertools.combinations, such as the following: from itertools import combinations l = [1, 2, 3, 4, 5] for i in combinations(l,2): print(list(i)) This generates the following: [1, 2] [1, 3] [1, 4] [1, 5] [2, 3] [2, 4] [2, 5] [3, 4] [3, 5] [4, 5]… Read More Is there a way to generate combinations, one at a time?

I have a string dt = ‘301 302 303’ how can I get different combinations of above string with considering only spaces while splitting the string. # output 301 302 303 301 302 301 303 302 303 301 302 303 >Solution : Please use itertools module turn the string to a list and then iterate… Read More python/string: how to get all the possible combinations in string considering only space for splitting the string

I want to write a REGEX that removes all combination of a group of characters from the end of strings. For instance removes "k", "t", "a", "u" and all of their combinations from the end of the string: Input: ["Rajakatu","Lapinlahdenktau","Nurmenkaut","Linnakoskenkuat"] Output: ["Raja","Lapinlahden","Nurmen","Linnakosken"] >Solution : How about something like this [ktau]{4}\b? https://regex101.com/r/BVwTcs/1 This will match at… Read More Remove all combination of set at the end of string REGEX

I have retail store transactional data and want to see what categories are bought together.

Let’s say I have 5 points in graph, v = [0,1,2,3,4]. The list with all possible combinations would look like this: [(), (0,), (1,), (2,), (3,), (4,), (0, 1), (0, 2), (0, 3), (0, 4), (1, 2), (1, 3), (1, 4), (2, 3), (2, 4), (3, 4), (0, 1, 2), (0, 1, 3), (0, 1,… Read More Discard some sets in list with all possible combinations

I am trying to do an algorithm where I find all the possible combination between two lists but I am not sure how do we call this type of combination in math: Input: List 1 : [a,b,c,d] and List 2 : [1,2,3,4] Desired output: [a1, a2, a3,a4, b2, b3, b4, c3,c4, d4] I am looking… Read More Combination between two lists using cartesian product with a small twist
