I have a pandas dataframe df which contains:
major men women rank
Art 5 4 1
Art 3 5 3
Art 2 4 2
Engineer 7 8 3
Engineer 7 4 4
Business 5 5 4
Business 3 4 2
Basically I am needing to find the total number of students including both men and women as one per major regardless of the rank column. So for Art for example, the total should be all men + women totaling 23, Engineer 26, Business 17.
I have tried
df.groupby(['major_category']).sum()
But this separately sums the men and women rather than combining their totals.
Just add both columns and then groupby:
(df.men+df.women).groupby(df.major).sum()
major
Art 23
Business 17
Engineer 26
