Question

Here is the problem I am working on. I need to write a py program that:

Calculates a Cartesian Product Output, A x B of 2 lists. I want to limit each list to 5 numbers. It is kind of working, but I can't help think that there is a simpler way to express this problem. Please advise...

Here is my code:

def CartesianProductOutput(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 = [1,2,3,4,5]

B = [1,2,3,4,5]

print(CartesianProductOutput(A,B))

Answer 1

HELLO!!

EXPLANATION:

• Through "itertools" module you can make iterative tasks like in our problem
• The function "product" is used to find the cartesian product of the given lists

CODE:

#importing product function from itertools module
from itertools import product
a=[1,2,3,4,5]           
b=[1,2,3,4,5]
x=[]          #an empty list 
product(a,b)  #using product function
for each in product(a,b):  #loop to append to the list
    x.append(each)      #appending to the empty list x
print(x)               #printing the list

OUTPUT:
