Concatenate strings from several rows using Pandas groupby

Question

I want to merge several strings in a dataframe based on a groupedby in Pandas.

This is my code so far:

import pandas as pd
from io import StringIO

         


        

Answer 1

we can groupby the 'name' and 'month' columns, then call agg() functions of Panda’s DataFrame objects.

The aggregation functionality provided by the agg() function allows multiple statistics to be calculated per group in one calculation.

df.groupby(['name', 'month'], as_index = False).agg({'text': ' '.join})
