Sure, you can create a sort-of logic to fit the existing naming, but it's still something you have to learn.

Imagine you were using Pandas for the first time, working through a tutorial, and you've just learned that pd.read_csv reads a csv into a dataframe.

Intuitively, what would you expect the corresponding output function to be called? I'd hazard that a vast majority of people would guess at some version of write_csv, and would experiment with either pd.write_csv, or df.write_csv.
