PandasdrillCounts with crosstab
A pandas exercise from Pandasdrill. Solve it with a Python editor in your browser running real pandas, and it is checked the moment you submit.
The task
Count the orders for each region (rows) and product (columns) with `pd.crosstab`.
What this exercise teaches
crosstab counts how often each pair of values appears. Missing pairs show 0 automatically, which makes it a quick way to build a frequency table.
A hint if you get stuck
The first argument of crosstab becomes the rows and the second becomes the columns.
