dataframe 按行 遍历

对于DataFrame按行遍历，可以使用iterrows()方法来实现。iterrows()方法会返回一个迭代器对象，该对象包含每一行的索引和数据。可以使用for循环来逐行处理数据。下面是一个示例代码：

import pandas as pd

# 示例数据
data = {'name': ['刘一', '陈二', '张三', '李四', '王五'],
        'age': [18, 19, 20, 21, 22],
        'height': [175, 176, 177, 178, 179]}
index = ['0001', '0002', '0003', '0004', '0005']
df = pd.DataFrame(data=data, index=index)
df.index.name = 'id'

# 按行遍历
for index, row in df.iterrows():
    print("Index:", index)
    print("Row:", row)

# 输出每行的索引值和对应的数据

这段代码会按行遍历DataFrame，并输出每行的索引值和对应的数据。你可以根据实际需求修改输出的内容或进行其他操作。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
