循环遍历Pandas数据帧行的有效方法

import pandas as pd

# 创建一个示例数据帧
data = {'Name': ['Tom', 'Nick', 'John'],
        'Age': [28, 32, 25],
        'City': ['New York', 'Paris', 'London']}
df = pd.DataFrame(data)

# 使用iterrows()方法循环遍历数据帧的每一行
for index, row in df.iterrows():
    print(f"Index: {index}")
    print(f"Name: {row['Name']}")
    print(f"Age: {row['Age']}")
    print(f"City: {row['City']}")
    print()

Index: 0
Name: Tom
Age: 28
City: New York

Index: 1
Name: Nick
Age: 32
City: Paris

Index: 2
Name: John
Age: 25
