[jamesbraza]

Is your feature request related to a problem? Please describe.

https://bandit.readthedocs.io/en/latest/blacklists/blacklist_calls.html#b311-random documents not to use pseudo-random generators. However, it doesn't document what to use instead.

As someone with limited security experience, I am not sure what to use instead of random.random().
