I have a list with 15 numbers in, and I need to write some code that produces all 32, combinations of those numbers. I've found some code by Googling that apparently does what I'm looking for, but I found the code fairly opaque and am wary of using it.

Plus I have a feeling there must be a more elegant solution. The only thing that occurs to me would be to just loop through the decimal integers 1— and convert those to binary, and use the binary representation as a filter to pick out the appropriate numbers. Have a look at itertools. Combinations are emitted in lexicographic sort order.

So, if the input iterable is sorted, the combination tuples will be produced in sorted order. Or -- if you want to get snazzy or bend the brain of whoever reads your code after you -- you can generate the chain of "combinations " generators, and iterate through that:. For each binary string, you pick all elements corresponding to a "1".

A List Of All Possible Combinations

In comments under the highly upvoted answer by Dan H, mention is made of the powerset recipe in the itertools documentation —including one by Dan himself. Howeverso far no one has posted it as an answer. Since it's probably one of the better if not the best approach to the problem—and given a little encouragement from another commenter, it's shown below.

The function produces all unique combinations of the list elements of every length possible including those containing zero and all the elements. Regardless, the fact that the iterable is ultimately turned into a list means it will work with generators unlike several of the other answers. I agree with Dan H that Ben indeed asked for all combinations.

Another issue is, if the input iterable is big, it is perhaps better to return a generator instead of everything in a list:. This is an approach that can be easily transfered to all programming languages supporting recursion no itertools, no yield, no list comprehension :. I thought I would add this function for those seeking an answer without importing itertools or any other extra libraries.

Here is yet another solution one-linerinvolving using the itertools. We don't realistically have to worry about running out of stack space since there's no way we could process all N! I know it's far more practical to use itertools to get the all the combinations, but you can achieve this partly with only list comprehension if you so happen to desire, granted you want to code a lot.

Please note that providing a helper function to those is advised because the prepend argument is static and is not changing with every call.

I'm listing the size of the combination before the actual list for each size, if what you need is simply the combinations without the size, as it appears in your sample output then try these other version of the code:.

The chain and combinations functions of itertools work wellbut you need to use Python 2. If you haven't used generators before, note that you loop through them as if they were a list, such as this:. The performance difference can be dramatic. If you compare the performance you'll see that the generator is much faster to create:. Note that it would still take some time to iterate through all the combinations in either case, but it can be a big win for you especially if you find what you're looking for early on.

The functions from the itertools module return iterators. All you need to do to convert these into lists is call list on the result. However, since you will need to call itertools.
