somelists = [
[1, 2, 3],
['a', 'b'],
[4, 5]
]
for factor in itertools.product(*somelists):
print(factor)
```

By analyzing numerous real-world circumstances, we’ve proven the best way to repair the Cartesian Product Of A Listing Python bug.

## How do you discover the Cartesian product of a listing in Python?

Sensible Knowledge Science utilizing Python We have now to seek out Cartesian product of those two lists. As we all know if two lists are like (a, b) and (c, d) then the Cartesian product will probably be {(a, c), (a, d), (b, c), (b, d)}. To do that we will use itertools library and use the product() operate current on this library.11-Oct-2021
