I know in most, if not all programming languages, integers, floats etc all have a maximum amount they can hold, either unsigned or signed. Eg pascal's int type can only hold up to 32768 ~.
What i wanted to know was, what is the limit on python's int and floating point variables. I tried a little program to produce extremely large numbers, but i ran into no errors. Does it even have limits on how big these variables can be ?
I looked in the documentation and couldn't find what i was looking for :/
Help would be greatly appreciated, thanks !

It's usually 2^31 - 1 on a 32-bit platform and 2^63 - 1 on a 64-bit platform.
In Python3, int has no max limit. Python2 has two integer types, int and long , but Python3 has only int . int in Python3 is equivalent to long in Python2, and there is no max limit.
To store integers, the computers need to use binary numbers to represent the integers. By using 8 bits, you can store up to 28 – 1 = 255 integers. To store both negative integers, zero, and positive integers, you need to reserve 1 bit for storing the sign, negative (-) and positive (+).
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.

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.
