Pandas version checks

Documentation problem
The third page of the official "Cheat Sheet" at https://github.com/pandas-dev/pandas/blob/main/doc/cheatsheet/Pandas_Cheat_Sheet.pdf has a section called "Changing Type". It lists df.as_type(type), however no such method exists; the correct method should be df.astype(type).
Suggested fix for documentation
The fix is straightforward: replace as_type with astype.
