There should be an easier way to use the query method to select missing values. Here's one hack to get it done.

Amazing pandas trick or stupid hack? Use the query method to filter for missing values by testing whether column values equal themselves. NaN == NaN evaluates as False! So, df.query(col != col) returns rows with missing values in col.

Pandas can be challenging for beginners because of its confusing documentation and unnecessary parameters.

Does anyone else find this confusing? Pandas Series have a single axis. Series methods shouldn't have an axis parameter as it does nothing.
