"""
sys:
Return the size of an object in bytes.The object can be any type of object.
All built-in objects will return correct results, but this does not have to
hold true for third-party extensions as it is implementation specific.

pandas/polars:
Returns the size of an object in KB/MB/GB. Checking the dtypes will be
informative (e.g., float64 likely to use more space than int8).
