如何按列分组并删除或分隔pandas中的值？

import pandas as pd

data = {'Name': ['John', 'Mike', 'Sarah', 'Mike', 'John'],
        'Age': [28, 32, 25, 32, 28],
        'City': ['New York', 'London', 'Paris', 'London', 'New York']}
df = pd.DataFrame(data)

df_grouped = df.groupby('Name').agg({'Age': lambda x: ', '.join(map(str, x))})

print(df_grouped)

import pandas as pd

data = {'Name': ['John', 'Mike', 'Sarah', 'Mike', 'John'],
        'Age': [28, 32, 25, 32, 28],
        'City': ['New York', 'London', 'Paris', 'London', 'New York']}
df = pd.DataFrame(data)

df_grouped = df.groupby('Name').agg({'Age': lambda x: ', '.join(map(str, x))})

print(df_grouped)
