Dataframe identify rows

I made a data frame from an xlsx spreadsheet, which has every month from Jan 1976- to Feb 2020 as columns, and as rows these variables.

Month-year

Population

Labour force 

Employment 

Full-time employment 

Part-time employment  

Unemployment 


Unemployment 

Participation%

Employment%

how do identify a row like ‘Participation%’ into my dataframe?

findfirst in the relevant column.
