如何在Python Pandas中进行嵌套循环类型的操作？

import pandas as pd

# 创建一个示例DataFrame
data = {'Name': ['Alice', 'Bob', 'Charlie'],
        'Age': [25, 30, 35],
        'City': ['New York', 'London', 'Paris']}
df = pd.DataFrame(data)

# 嵌套循环操作
for index, row in df.iterrows():
    for column, value in row.iteritems():
        print(f"Index: {index}, Column: {column}, Value: {value}")

Index: 0, Column: Name, Value: Alice
Index: 0, Column: Age, Value: 25
Index: 0, Column: City, Value: New York
Index: 1, Column: Name, Value: Bob
Index: 1, Column: Age, Value: 30
Index: 1, Column: City, Value: London
Index: 2, Column: Name, Value: Charlie
Index: 2, Column: Age, Value: 35
Index: 2, Column: City, Value: Paris
