Unresolved reference 'UserAgent'

The error "Unresolved reference 'UserAgent'" typically occurs when the code tries to use the 'UserAgent' class or variable, but it cannot find its definition. This error often happens when the required module or library is not imported correctly.
To resolve this issue, you should check if you have imported the necessary module that contains the 'UserAgent' class. In Python, you can import modules using the `import` statement. For example, if 'UserAgent' is part of the 'requests' library, you can import it as follows:
```python
import requests
# Now you can use UserAgent from the requests module
```
Make sure that the required module is installed in your environment. You can use package managers like pip to install missing modules. For example, to install the 'requests' library, you can run the following command:
```
pip install requests
```
By importing the required module and ensuring it is installed, the "Unresolved reference" error should be resolved.
