Hi everyone,

I am quite a begginer using Python , and I am struggling to extract the categorical variables (the columns) of my df that contain 6 or less unique values. I have many columns so I search a way to avoid doing it column by columns...

Thank you so much !

If you want to find all unique values for entire data frame, you can use pd.unique, e.g.

pd.unique(df.values.ravel())

df is your data frame.
