Hi, the author here. Thanks for posting this! The Python behind the scenes series covers how different aspects of Python are implemented in the CPython interpreter. This time we'll ask and answer the following question: How is Python able to support arbitrary large integers? More specifically, we'll learn:
* How CPython represents arbitrary-precision integers.
* How CPython implements arbitrary-precision arithmetic, such as addition and multiplication.
* How CPython's implementation of arbitrary-precision arithmetic compares to other implementations.
