combinations = list(itertools.combinations(deck, 9))
i try to find all this combinations then i will load this combinations in a csv file but kaggle gives me this error message:
Your notebook tried to allocate more memory than is available. It has restarted.
itertools.combinations
create an iterator that allows you to iterate over each value without having to create a list and store each value in memory.
You can use the csv
module to write each combination as a line.
If you don't want an empty line between each combination, don't forget to use the newline=''
