I'm trying to clean one of my dataframe and need help grouping it by the attributes of a given column. What I've found online hasn't helped so far. Right now my line of code follows the pattern:

df.groupby('column1')

I also tried square brackets around my column name inside the parentheses and neither one is grouping the attributes. The resulting DataFrame is unchanged. Does anyone know the fix for this?

I had the same sort of issue for a general groupby commands. However I also applied a function in part of my groupby command which sorted it fine. I am not sure exactly what you are looking to group it by or the purpose, but my code was along the lines of:

df.groupby('column name').mean()['column 2 name']
