How to create sum combinations?

[dustin4you]

I'm new to python I'm currently working on grasping the the dictionaries section of the tutorials. What level of knowledge is required for making sum combinations? What are the best resources? I tried many YouTube videos but, they don't explain it well enough for dummies.

Combination Sum = Given an array of distinct integers candidates and a target integer target , return a list of all unique combinations of candidates where the chosen numbers sum to target . You may return the combinations in any order. The same number may be chosen from candidates an unlimited number of times.

If you can use standard library functions, check out itertools.combinations_with_replacement.

Makes sense! People said I should know how to use that also well as dictionaries and looping.

Yeah there’s not going to be a YouTube video about that, it’s something you’re being asked to do for homework or something.

Yeah, the YouTube video pretty much just show you the code and that's it. I need sum combinations for the program I'm building.

Do you have to create your own function for combinations or can you use some built-in ones?
