Pandas Quiz

Very specifically, what is happening with the following subset selections and why does the first one work and not the second?

df[['col1', 'col2']]

df['col1', 'col2']

This takes deep knowledge of python and pandas

Our 4-week live cohort Master Pandas class is running. We use a "flipped-classroom" model where students watch videos, read text, & attempt exercises BEFORE class.

During class, we work through student questions in a highly interactive environment

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

[Teddy Petrou @TedPetrou]

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.

[Dunder Data @DunderData]

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

[Teddy Petrou @TedPetrou]

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