如何在Pandas中用标签分隔行？

import pandas as pd

data = {'Name': ['Tom', 'Nick', 'John', 'Tom', 'John'],
        'Age': [20, 21, 19, 20, 18],
        'City': ['New York', 'Paris', 'London', 'New York', 'London']}
df = pd.DataFrame(data)

grouped = df.groupby('Name')

for name, group in grouped:
    print(name)
    print(group)
