Python Number Limit

There used to be a limit in earlier versions of Python for int. But, this is dropped as Python treats integers as objects. So, although Python allocates 32 bits for the value object reference is pointing to, as the value goes beyond 2^32 it can keep moving up all the way up to the size of RAM on your computer.

See the sys module:

import sys
dir(sys)
print sys.maxint
help(sys.float_info)

and so on.

Earlier Versions had a limit on int but its removed now, so you can say there is no limit, it depends on the memory of your computer. Check this article.
