RSA How to recover a key in Java and encrypt data from one created in Python?

Question

Python

Created private and public keys in Python:

import rsa
(pubkey, privkey) = rsa.newkeys(512)

I pass the public to the client in Java (modulus, exponent). How to restore the object for encrypting the message using these parameters?
In Python, the same problem, if there is an object, it is easily encrypted, but how to get this object from these parameters?
Or do you need something else?
