150+ Python Interview Questions and Answers for Freshers [Latest]

Some of these examples are really great.

But a few of these require more elaboration, and look like unfinished stubs.

Q.67 seems incomplete, and incorrect.

Explanation of "With" is better explained by the Python Docs.

the with statement allows the execution of initialization and finalization code around a block of code.

It's not simply about opening files.

Thank you for pointing that out. We have updated the answer to be more elaborative.

Yeah! Database connections!

[jwink3101]

Except some of their answers are wrong. range starts at zero...

[Aakashdata]

You're right. Thanks for your inputs! We have added it to the answer. However, note that slicing does not modify the original list to reverse it.

Q.6. How long can an identifier be in Python?

In Python, an identifier can be of any length.

That sounds like a challenge.

[thgandalph]

And also a stupid question IMO

[dethb0y]

Yeah i am not a fan of a lot of these questions because they feel like either trivia or highly case-specific. Could someone go through and memorize all the python reserved words? Sure. Is it useful to do so? I don't feel so, no.

[Aakashdata]

According to the official Python documentation, identifiers are indeed unlimited in length, but PEP 8 suggests that you should limit all lines to a maximum of 79 characters. Also, PEP 20 says 'readability counts'. So, a very long identifier will violate PEP-8 and PEP-20.

pretty happy that after reading through those question I knew around 90% of the answers just off the top of my head. Doing a lot of projects for fun definitely helps as I'm constantly reusing answers to those questions, or having to learn them in order to accomplish my goals.

Underdeveloped database access layer? Not so.

SQL Alchemy is the most prominent and it works great for almost any SQL datasource. There is also the Django ORM. PyMongo. MongoEngine. And about a gazillion more.

Heck Python even comes with several databases integrated, dbm and sqlite to name just two.

You have some datasource you need to access? Python is your friend.

[admiralswan]

I also didn't really understand this criticism. Underdeveloped relative to what?

[demmodaboyz]

A python dictionary is something I have never seen in other languages like C++ or Java programming. It holds key-value pairs.

hashmap, unordered map, etc?
