这个错误是因为 Python 在解析字符串时,会将反斜杠视为转义字符,例如 \n 代表换行符。而在你的路径中出现了反斜杠,导致 Python 无法正确解析该路径。可以通过以下两种方法解决该问题:
1. 在路径前加 r,表示该字符串是 raw string,不需要转义:
```python
df.to_excel(r'C:\Users\万万众\Desktop\新建 XLS 工作表.xls', index=False)
```
2. 将所有反斜杠改成双反斜杠:
```python
df.to_excel('C:\\Users\\万万众\\Desktop\\新建 XLS 工作表.xls', index=False)
```
以上两种方法都可以解决该问题,选择其中一种即可。

File "C:\Users\lenovo\PycharmProjects\pythonProject\Guiyi.py", line 11, in <module> df1.to_excel(file, index=False)
This error message indicates that there is an issue with writing a pandas dataframe (df1) to an Excel file (specified by the 'file' variable) in the Guiyi.py script.
The error is likely occurring due to one of the following reasons:
1. The 'file' variable is not properly defined or does not have the correct file path/name. Check that the 'file' variable is correctly defined as a string with the file path and name, and that the file already exists or can be created.
2. There is an issue with the pandas library or the Excel writer. Check that pandas and any required dependencies are properly installed and up-to-date. Additionally, ensure that the Excel file is not currently open or being used by another process, as this can cause issues with writing to the file.
3. There is an issue with the data being written to the Excel file. Check that the dataframe (df1) is properly formatted and does not contain any missing or incorrect values that may be causing issues with writing to the Excel file.
To diagnose the issue further, you can try adding print statements or debugging tools to the code to help identify where the error is occurring and what may be causing it.

这个错误通常是因为在文件路径中使用了反斜杠"\", 但是反斜杠在Python中被视为转义字符,需要将其替换为斜杠"/"或双反斜杠"\\".
你可以将文件路径修改为以下形式:
```python
df = DataFrame(pd.read_excel('C:/Users/万万众/Desktop/unsdg_2002_2021.csv'))
```
或者使用双反斜杠:
```python
df = DataFrame(pd.read_excel('C:\\Users\\万万众\\Desktop\\unsdg_2002_2021.csv'))
```
或者使用原始字符串:
```python
df = DataFrame(pd.read_excel(r'C:\Users\万万众\Desktop\unsdg_2002_2021.csv'))
```
