I am working on a pandas dataframe with 168 columns. First three columns contain name of the country, latitude and longtitude. Rest of the columns contain numerical data. Each row represents a country but for some countries there are multiple rows. I need to aggregate those rows by summing. I can aggregate first three columns with following code:
df = df.groupby('Country', as_index=False).agg({'Lat':'first','Long':'first'})
However, I couldn't find a way to include in that code remaining 165 columns without explicitly writing all the column names. In addition, column names represent dates and are named like 5/27/20
, 5/28/20
, 5/29/20
, etc. So I need to keep the column names.
How can I do that? Thanks.
Maybe you can generate the dictionary from the column names:
df = df.groupby('Country', as_index=False).agg({c: 'first' for c in df.columns})
