import pandas as pd

certificates_earned = pd.DataFrame({
    'Certificates': [8, 2, 5, 6],
    'Time (in months)': [16, 5, 9, 12]
})
names = ['Tom', 'Kris', 'Ahmad', 'Beau']

certificates_earned.index = names
longest_streak = pd.Series([13, 11, 9, 7], index=names)
certificates_earned['Longest streak'] = longest_streak

print(certificates_earned)
