这个错误提示是因为您使用了一个元组作为列名来访问数据，但 DataFrame 中不支持这种方式。您需要使用方括号 `[]` 来分别指定列名，或者使用 `loc[]` 方法来访问一个或多个列。请尝试以下代码：

import pandas as pd

data = pd.read_csv('your_data.csv')  # 读取数据
data[['tip', 'total_tips']].fillna(data[['tip', 'total_tips']].mean(), inplace=True)

或者：

import pandas as pd

data = pd.read_csv('your_data.csv')  # 读取数据
data.loc[:, ['tip', 'total_tips']] = data.loc[:, ['tip', 'total_tips']].fillna(data.mean())

这两种方式都可以对指定的两列数据进行缺失值填充。

Could not import runpy module Traceback (most recent call last): File "/data/Python-3.10.11/Lib/runpy.py", line 15, in <module> import importlib.util File "/data/Python-3.10.11/Lib/importlib/util.py", line 14, in <module> from contextlib impor

It seems like there is an error with the importlib module in your Python installation. This module is responsible for loading and importing modules dynamically at runtime.

One possible solution is to reinstall Python or try updating to a newer version of Python that includes the necessary updates to the importlib module.

Another solution is to try reinstalling the importlib module using pip. You can do this by running the following command:

pip install importlib

If none of these solutions work, you may want to seek help from the Python community or a Python developer.

Traceback (most recent call last): File "d:\work\xdj.py", line 17, in <module> Initdata.setAccount() File "d:\work\getEnvAndAcco.py", line 14, in setAccount dataInit.Initdata() File "d:\work\DataInit.py", line 21, in Initdata data = f.readline() ValueError: I/O operation on closed file.

这个错误发生在你的代码中。根据错误信息，看起来是在"getEnvAndAcco.py"文件的第14行调用了一个叫做"setAccount"的函数，该函数在"DataInit.py"文件的第21行初始化数据时出现了问题。

具体来说，错误是在第21行的`f.readline()`操作中发生的，它提示文件已关闭。这意味着在这之前，你可能已经关闭了文件或者没有正确打开文件。请确保在读取文件之前，先打开文件并保持它处于打开状态。

如果你能提供更多的代码片段或者上下文信息，我可以给出更具体的帮助。
