I need to write the function dot(L, K) that should output the dot product of the lists L and K. If these two input lists are not of equal length, dot should output 0. If these two lists are both empty, dot also should output 0. You should assume that the input lists contain only numeric values. This is what I have so far. Cartesian product of a dictionary of lists. This is a very neat code to quickly generate unit test cases (cross-validation set style!) – gaborous Jul 7 '15 at How to create a 3 dimensional dictionary from 3 lists in Python. 3. nesting to a dynamic depth in Python. 0. I'm not sure exactly what you mean. If a and b are not sets, and have duplicate elements within themselves, then yes, this can produce duplicate entries.[(x, y) for x in [1, 1] for y in [2]] would produce [(1, 2), (1, 2)].But that's the result of applying an mathematical operation defined on sets on non-set input.

Cross product two lists python

Let A and B be two sets, Cartesian productA × B is the set of all ordered pair of Given two finite non-empty sets, write a program to print Cartesian Product. [email protected]{##}&. Takes two lists of characters as input. ->a,b{www.key64.nett b} Takes both inputs as strings or as arrays of individual characters. Documentation: Python 3 - www.key64.nett . For Python and older: . The result of both is an iterator, so if you really need a list for furthert processing, use. Do a list comprehension, iterate over both the lists and add the strings, like list3 = [i+str(j) for i in list1 for j in list2]. You're looking for www.key64.nett if you're on (at least) Python >>> import itertools >>> a=[1,2,3] >>> b=[4,5,6] >>> www.key64.nett(a,b) product. If you can use the built-in itertools module, then www.key64.nett is probably the easiest, but it probably not allowed. www.key64.nett creates an. Cartesian Product Of Sets — A Real Life Use Case In Python . To keep some order, I'll use lists as follows by changing the curly braces to. I'm wondering wy the Python devs haven't defined that multiplying two lists should return their cartesian product. It, would be pretty useful -. Create two lists i = [1,2,3,4,5] j = [1,2,3,4,5] List every single x in i with every single y (i.e. Cartesian product) [(x, y) for x in i for y in j]. [(1, 1), (1.To compute the cross product using www.key64.net, the dimension (length) of the array dimension which defines the two vectors must either by two or www.key64.net quote the documentation: If a and b are arrays of vectors, the vectors are defined by the last axis of a and b by default, and these axes can have dimensions 2 or Note that the last axis is the default. I'm solving exercise 4 from Discussion 3 of Berkley's CS 61A () (see page 4). Fill in the definition of www.key64.netian_product takes in two tuples and returns a tuple that is the Cartesian product of those tuples. To find the Cartesian product of tuple X and tuple Y, you take the first element in X and pair it up with all the elements in Y. I need to write the function dot(L, K) that should output the dot product of the lists L and K. If these two input lists are not of equal length, dot should output 0. If these two lists are both empty, dot also should output 0. You should assume that the input lists contain only numeric values. This is what I have so far. I'm not sure exactly what you mean.

You do not need recursion. All you need to do is build up a set of intermediate solutions. Here is a non-recursive solution in Python: # This does NOT use recursion! def all_comb(list_of_lists): # We start with a list of just the empty set.
