Sonar Could for Azure DevOps pull request
- Code:

```auto
style = "style = 'background-color : pink;'"
#SonarCloud alert: Remove the unused local variable "style".
key_name = k.replace("_", "\\_")
#SonarCloud alert: Remove the unused local variable "key_name".
body_text += f'''<tr {style if Counter(v.values()).get('FAIL', 0) != 0 else ''}><td>{key_name}</td><td>{Counter(v.values()).get('PASS', 0)}</td><td>{Counter(v.values()).get('FAIL', 0)}</td></tr>'''

```

The variable “style” and “key\_name” are used in the f-string (body\_text) but still get this error and block the PR

hello @wzmf399443,

welcome to our community!  
I’m able to reproduce the false positive you reported and I created ticket [SONARPY-815](https://jira.sonarsource.com/browse/SONARPY-815) to keep track of it.

Thanks a lot!
