如何使用pandas中的值范围将多行分组为一组？

import pandas as pd

data = {'Name': ['John', 'Emma', 'John', 'Emma', 'John', 'Emma'],
        'Value': [10, 20, 30, 40, 50, 60]}
df = pd.DataFrame(data)

bins = [0, 25, 50, 75, 100]  # 定义值范围
labels = ['Group 1', 'Group 2', 'Group 3', 'Group 4']  # 定义分组标签
df['Group'] = pd.cut(df['Value'], bins=bins, labels=labels)  # 将数据框中的值按照值范围分组

print(df)

   Name  Value    Group
0  John     10  Group 1
1  Emma     20  Group 1
2  John     30  Group 2
3  Emma     40  Group 2
4  John     50  Group 3
5  Emma     60  Group 3
