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.

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.

This had, by far, the largest impact on me becoming an expert.
It forced me to master the entire library and do so effectively and efficiently
