How to sum the rows of a dataframe and create a sub row below

Question

I am trying to take several numbers from a few different columns of a data frame and sum them and create a new row called "Total" directly below the last line. Below are some example data that I am working with.

import pandas as pd
option = pd.DataFrame(['Option1','Option2','Option3','Option4'])
Volume = pd.DataFrame([1234,23423,2331,23135])
dataframe1 = pd.concat([option, Volume],axis=1)

You will see that I am looking at a two-column dataframe with the "Options" column and then a numerical value. The end goal is to have a "Total" column at the end of the option 4 row this will need to be an aggregate of all the numbers in Options 1-4. Please let me know the best way to go about this! Thank you

Answer 1

totalcount = dataframe1.iloc[:,1].sum()
dataframe1.loc[len(dataframe1.index)] = ['Total', totalcount]  # This is for Row
dataframe1["Total"] = totalcount  # This is for Column
print(dataframe1)
