Explain in simple terms what idxmin and idxmax do in the short program below. When would you use these methods?
data = pd.read_csv('data/gapminder_gdp_europe.csv', index_col='country')
print(data.idxmin())
print(data.idxmax())
data, idxmin will return the index value corresponding to each column’s minimum; idxmax will do accordingly the same for each column’s maximum value.
You can use these functions whenever you want to get the row index of the minimum/maximum value and not the actual minimum/maximum value.
