>             Project: Apache Airflow
>          Issue Type: Bug
>          Components: utils
>    Affects Versions: 1.10.6
>            Reporter: Jakob Homan
>            Priority: Minor
>              Labels: ccoss2019, newbie

> Note: This ticket's being created to facilitate a new contributor's workshop 
> for Airflow. After the workshop has completed, I'll mark these all available

> airflow/utils/strings.py:27
> {code:java}
> def get_random_string(length=8, choices=string.ascii_letters + string.digits):
>     '''
>     Generate random string
>     '''
>     return ''.join([choice(choices) for i in range(length)]) {code}
> Here we use an `i` for a placeholder variable, but this gets flagge as an 
> unused variable.  We can replace the `i` with `_` and avoid this warning.
