# Itertools.Product() in Python | HackerRank Solution

Hello coders, today we are going to solve Itertools.Product Hacker Rank Solution in Python.

## Problem

This tool computes the cartesian product of input iterables.

It is equivalent to nested for-loops.

For example, product(A, B) returns the same as ((x,y) for x in A for y in B).

```>>> from itertools import product
>>>
>>> print list(product([1,2,3],repeat = 2))
[(1, 1), (1, 2), (1, 3), (2, 1), (2, 2), (2, 3), (3, 1), (3, 2), (3, 3)]
>>>
>>> print list(product([1,2,3],[3,4]))
[(1, 3), (1, 4), (2, 3), (2, 4), (3, 3), (3, 4)]
>>>
>>> A = [[1,2,3],[3,4,5]]
>>> print list(product(*A))
[(1, 3), (1, 4), (1, 5), (2, 3), (2, 4), (2, 5), (3, 3), (3, 4), (3, 5)]
>>>
>>> B = [[1,2,3],[3,4,5],[7,8]]
>>> print list(product(*B))
[(1, 3, 7), (1, 3, 8), (1, 4, 7), (1, 4, 8), (1, 5, 7), (1, 5, 8), (2, 3, 7), (2, 3, 8), (2, 4, 7), (2, 4, 8), (2, 5, 7), (2, 5, 8), (3, 3, 7), (3, 3, 8), (3, 4, 7), (3, 4, 8), (3, 5, 7), (3, 5, 8)]```

You are given a two lists A and B. Your task is to compute their cartesian product AXB.

## Example

```A = [1, 2]
B = [3, 4]

AxB = [(1, 3), (1, 4), (2, 3), (2, 4)]```

Note: A and B are sorted lists, and the cartesian product’s tuples should be output in sorted order.

## Input Format

The first line contains the space separated elements of list A.

The second line contains the space separated elements of list B.

Both lists have no duplicate integer elements.

0 < A < B
0 < B < 30

## Output Format

Output the space separated tuples of the cartesian product.

Sample Input

``` 1 2
3 4```

Sample Output

` (1, 3) (1, 4) (2, 3) (2, 4)`

## Solution – Itertools.Product() in Python – Hacker Rank Solution

```# Enter your code here. Read input from STDIN. Print output to STDOUT
from itertools import product
a = map(int, input().split())
b = map(int, input().split())

print(*product(a, b))
```
