I have a list of 20 products and want to generate the list of all possible combinations of 4 unique products. the order is not important example (a,b,c,d) = (b,d,a,c)... and only one should be listed.

Thank you

Ned

I'm not a programmer and a beginner trying to learn Python.

I calculated 4845 combinations but would like to use python to generate them.

This can be solve using the itertools package, using itertools.combinations(iterable, r) where iterable is the list of elements that you want to calculate the comb, and r is the length subsequences of elements

import itertools

# You define the list of your products
products = [1, 2, 3, 4, 5, 6, 7,]

comb = list(itertools.combinations(products, 4))

If you want to guarantee that there is not any repetition:

import itertools

# You define the list of your products
products = [1, 2, 3, 4, 5, 6, 7,]

# This will remove the duplicate products
products = list(set(products))

comb = list(itertools.combinations(products, 4))

Please refer to https://docs.python.org/3/library/itertools.html#itertools.combinations
