In one part of my code, I use if entry['partnr'] is not None:, in others, if not entry['partnr'].startswith(foo): and it just doesn't feel right.
Yet it looks like both are stylistically correct.
I could fix that by storing the result of the startswith in another variable, but that's just obscuring things.

This question rather belongs on CodeReviewMaxPowers 16 secs ago
@Mast Looks fine IMO, if entry['partnr']: Optional[str]. We don't have a ?. in Python to remove the null check.

Interview processes run the gamut from a few conversations, to hours of writing code on a whiteboard, to evaluative social events with the team. It can all seem very mysterious and nerve-wracking from the outside. But here’s the big secret: No matter what kind of process you step into, the hiring team, really, is only trying to figure out three things.

When the theorem states "infinite" it could be more than 10 minutes, depending on the complexity (length) of the control string. You have some options to "see" a result: Reduce the length of the control string in order to have less permutations, or increase the tries per second. This could be done using a more powerful machine or using parallel computations. BTW, I also think this should be on CodeReview — gustavovelascoh 39 secs ago
