I think the maximum integer in python is available by calling sys.maxint.

What is the maximum float or long in Python?

long-integer max int python

In python 3 there is no sys.maxint There is a sys.maxsize

>>> sys.maxsize
2147483647

That does not mean that the maximum int is limited to 2 billion! It means that the size of the object containing the integer has a maximum size of 2 billion bytes. I.e. a very very large number

For float have a look at sys.float_info

>>> sys.float_info
sys.float_info(max=1.7976931348623157e+308, max_exp=1024, max_10_exp=308, min=2.2250738585072014e-308, min_exp=-1021, min_10_exp=-307, dig=15, mant_dig=53, epsilon=2.220446049250313e-16, radix=2, rounds=1)

And specifically sys.float_info.max

>>> sys.float_info.max
1.7976931348623157e+308
