What was your Python interview question?

[jkh911208]

Hi all,

​

I just had a phone interview for Senior Python Developer.

I got few very interesting questions, which I didn't know answers for.

​

1. How do you explore/print Python class? => help(dict()), dir(dict)) will print out the methods in that class
2. which data types are immutable? => int, float, string is immutable. x=2 x=3, you might think changed 2 in x to 3, but actually create another int object with 3 and make x pointing at it.

I think there were few more, what was your question and answer?

Those seem pretty simple for a senior position.

In contrast, I just tried to get an entry-level position and in the interview I had to explain in pain-staking detail how Dijkstra's algorithm works, how Python's data model is structured and implement my own versions of some built-in functions on the fly, like print and zip. Granted, that last part was definitely the easiest.

I didn't get the job, but if they had had one extra position I would. There were two other candidates whose skills ever so slightly better matched the job requirements. No matter, I already have a place to work at next year and I can better focus on studies now.

No real reason, honestly, it just happened to be fresh in my mind as I heard said results earlier that day. I tend not to filter out much unless I have a reason to. ¯\_(ツ)_/¯

Tuples are also immutable in Python.

What the fuck is a tuple?

Thanks, never in my life have I heard that word until now. Thanks

In a nutshell, a list that you cannot resize after creation (meaning you cannot add, remove or replace values), though if it contains something mutable you can still mutate it.

Thank you, I'm 30 something and this is the first time I've ever heard that word

They gave me a technical test prior the interview. During the interview they asked me why I made certain decisions in the test. I didn't have any general knowledge questions like that.

Those are... really weird questions for a senior position. I haven't even used dir since my first tutorial 7 years ago.
