That wraps up the python list intersection. If it doesnt, then well do nothing. If it does, then we add it to our new list. O(1) but memory O(n). Manually raising (throwing) an exception in Python. This does not take advantage of the ordered structure of the lists given in the prompt: you could exploit that structure to reduce the time complexity to O(n + m) as they always increase and never overlap, meaning you can do all comparisons in a single pass. for 2.4, you can just define an intersection function. Getting intersection of two lists in python. but remember: 'Thus spoke the Lord: "Thou shalt indent with four spaces. After that, you can just pass lists (or any other iterable) to the. Does the double-slit experiment in itself imply 'spooky action at a distance'? Note there is more than one solution and hopefully you can solve the problem and then iteratively improve upon it. Union of a list means, we must take all the elements from list A and list B (there can be more than two lists) and put them inside a single new list. Check out this in-depth tutorial that covers off everything you need to know, with hands-on examples. We will be using both filter and lambda to perform intersection between two lists. An rather elegant solution can be using sets and their intersection: You are not looking over all of Z2 at most you arrive at i=2 so you never arrive at the last item in Z2 which is the one you are looking for (which should be i=4, but len(Z1) < 4). It doesn't preserve the order, but it'll consider the duplicates: when we used tuple and we want to intersection. Just loop over both, brute force solution: Sets are faster (see Michael's answer) but the any() function with a comprehension can check the condition in a simple (albeit naive) way: You could also benefit from set performance by converting Z1 to a set beforehand. We can also use a boolean method, using the & operator, to find the intersection between two sets. Here, inside the statement i for i in A if i in B, we want to append element i inside our list intersect for every element in A, if the same element exists in B.
