I have a program that was suppose to do the following:

Compute their Cartesian product, AxB of two lists. Each list has no more than 10 numbers.

For example, given the two input lists: A = [1,2] B = [3,4]

then the Cartesian product output should be: AxB = [(1,3),(1,4),(2,3),(2,4)]

***********

The code that I have is this: (Thanks to other great answerers like you all)

What I need: Is for the code below to have the user prompted to enter the two list, not have them automatically entered.

def CartesianProduct(A,B): lst = [] for x in A: t = [] t.append(x) for y in B: temp = [] for x in t: temp.append(x) temp.append(y) lst.append(temp) return lst A = [1,2] B = [3,4]

print(CartesianProduct(A,B))
