I just started working with python pandas and am trying to achieve the following:
I have a dataframe d that contains the rows Country and Botnet. For each value of Country, I want to calculate how many distinct Botnet values exist.
I know that I can receive the distinct country values as follows:
d['Country'].unique()
I do not know however how I can now transform this to receive the length of all the unique botnet values sorted per country. Is this even possible in Pandas?
