决定你想要将DataFrame中的哪一列或哪些列转换为列表。你可以通过列名来指定。 python # 选择 'Name' 列 column_to_convert = 'Name' 使用.tolist()方法将选定的列转换为列表: 使用Pandas的.tolist()方法将选定的列转换为Python列表。 python #将 'Name' 列转换为列表 name_list
先通过values属性将DataFrame转换为NumPy数组,然后再调用tolist()方法将数组转换为列表。这是一种简单直接的方式,适用于快速将整个DataFrame转换为嵌套列表,每个内部列表代表DataFrame中的一行数据。 import pandas as pd # 创建一个示例DataFrame df = pd.DataFrame({ '名字': ['小明', '小红', '小张'], '年龄...
