Who _are_ we, as data practitioners? What is it we actually _do_ ?

Today's #databs mishap. Tableau can automatically convert strings to dates, right? Turns out if your date is in the form "Jan-88", then the ONLY short code for September that Tableau will accept is "Sept", NOT "Sep".

This explains all the NULL values and gaps in my time series 😭

In addition to showing column data types in the dataframe, @pola.rs allows you to get dictionary of data types where key is the column name and value is the data type.

This is especially helpful when you're writing data to #database and want the schema to be maintained.

You're a teacher who isn't pleased with the range of scale for the grades of your students.

So you set the min for the lowest grade at 60 and the max for the highest at 90.

Here's how to do just that in @pola.rs

Text matching in @pola.rs is not only possible but also super easy.

Here I get the rows that contain the text in Mills in manufacturer column.
