Polars DataFrame memory size in Python

Question

Was wondering about the size of particular polars DataFrames. I tried with:

from sys import getsizeof

getsizeof(df)
Out[17]: 48
getsizeof(df.to_pandas())
Out[18]: 1602923950

It appears all polars df are 48 bytes? Confused.

Answer 1

Using the polars.DataFrame.estimated_size() method we can get the size of the dataframe similar to pandas.info().
