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.
Unresolved reference 'PCV'
The error message "Unresolved reference 'PCV'" typically occurs when you try to use a variable, function or class that has not been defined or imported in your Python program.
To resolve this error, you should check your code and make sure that you have defined or imported the necessary modules or packages that contain the 'PCV' reference. If you are using a third-party library or package that contains the 'PCV' reference, you may also need to install it using pip or another package manager.
If you are still having trouble resolving the issue, please provide more details about your code and the context in which the error is occurring, so that I can provide more specific guidance.
