This error usually occurs when you try to use a variable or function that has not been defined or imported. In this case, it seems like you are trying to use the "string" module, but it has not been imported.
To resolve this issue, you can import the "string" module at the beginning of your code:
```python
import string
# Your code here
```
Alternatively, if you only need specific functions or constants from the "string" module, you can import them directly:
```python
from string import function_name, constant_name
# Your code here
```
Make sure that the "string" module is installed in your Python environment. You can check this by running `pip show string` in your command prompt or terminal.
