I'm curious about how Python manages integer overflow, especially in contrast to languages like C or C++. I understand that C and C++ have fixed-size integers that can overflow, but Python seems to handle integers differently. How does Python's approach prevent overflow?

Python uses a data structure called bignums to handle integers. Unlike C or C++, which have fixed 32- or 64-bit integer representations, Python integers can grow dynamically as needed. This means they won't overflow as long as there's enough memory available. It's a bit different from traditional integer handling, but it's similar to how lists and dictionaries work in Python too.
Is there a theoretical limit on how large a Python integer can be?
