Answer 1

Note that for large values, hex() still works (some other answers don't):

x = hex(349593196107334030177678842158399357)
print(x)

Python 2: 0x4354467b746f6f5f736d616c6c3f7dL
Python 3: 0x4354467b746f6f5f736d616c6c3f7d

For a decrypted RSA message, one could do the following:

import binascii

hexadecimals = hex(349593196107334030177678842158399357)

print(binascii.unhexlify(hexadecimals[2:-1])) # python 2
print(binascii.unhexlify(hexadecimals[2:])) # python 3
