53 python interview questions and answers

But by and by pap got too handy with his hick’ry, and I couldn’t stand it. I was all over welts. He got to going away so much, too, and locking me in. Once he locked me in and was gone three days. It was dreadful lonesome. I judged he had got drownded, and I wasn’t ever going to get out any more. I was scared. I made up my mind I would fix up some way to leave there.

I had tried to get out of that cabin many a time, but I couldn’t find no way. There warn’t a window to it big enough for a dog to get through. I couldn’t get up the chimbly; it was too narrow. The door was thick, solid oak slabs. Pap was pretty careful not to leave a knife or anything in the cabin when he was away; I reckon I had hunted the place over as much as a hundred times; well, I was most all the time at it, because it was about the only way to put in the time.

But this time I found something at last; I found an old rusty wood-saw without any handle; it was laid in between a rafter and the clapboards of the roof. I greased it up and went to work. There was an old horse-blanket nailed against the logs at the far end of the cabin behind the table, to keep the wind from blowing through the chinks and putting the candle out.

He said he would like to see the widow get me. He said he would watch out, and if they tried to come any such game on him he knowed of a place six or seven mile off to stow me in, where they might hunt till they dropped and they couldn’t find me. That made me pretty uneasy again, but only for a minute; I reckoned I wouldn’t stay on hand till he got that chance.

Python questions for data scientist and software engineers

Not so long ago I started a new role as a “Data Scientist” which turned out to be “Python Engineer” in practice.

I would have been more prepared if I’d brushed up on Python’s thread lifecycle instead of recommender systems in advance.

In that spirit, here are my python interview/job preparation questions and answers. Most data scientists write a lot code so this applies to both scientists and engineers.

Whether you’re interviewing candidates, preparing to apply to jobs or just brushing up on Python, I think this list will be invaluable.

Questions are unordered. Let’s begin.

What is the difference between a list and a tuple?

I’ve been asked this question in every python / data science interview I’ve ever had. Know the answer like the back of your hand.

  • Lists are mutable. They can be modified after creation.
  • Tuples are immutable. Once a tuple is created it cannot by changed
  • Lists have order. They are an ordered sequences, typically of the same type of object. Ie: all user names ordered by creation date, ["Seth", "Ema", "Eli"]
  • Tuples have structure. Different data types may exist at each index. Ie: a database record in memory, (2, "Ema", "2020–04–16") # id, name, created_at

    Syntax: list_1 = [10, ‘Chelsea’, 20] Syntax: tup_1 = (10, ‘Chelsea’ , 20)
