海外TECH	DEV Community	Python/Django Developer Interview Questions and Answer (#1)	https://dev.to/manishanaidu/python-django-developer-interview-questions-and-answer-1-3l82	Python Django Developer Interview Questions and Answer Most of the software engineers are intimidated by technical rounds and I have recently started to give interviews So this time I am planning to write up all the questions I get asked in my technical rounds Hope this will be helpful to some of you to get an idea on what type of questions are being asked Use this series as a guide to prepare and ace that interview Some questions might be specific to Python and Django but most of them will be applicable to any software engineering role and web application developers This interview was for a Python developer role and they were looking for a candidate proficient in Django too hence you will be seeing many questions related to Django architecture and design as well Let s work on a recursive implementation of Fibonacci series passed n return the fibonacci value at the nth position Solution Fibonacci series are created in one of the two ways iterative and recursive Interviewer was looking for a recursive solution only def fibonacci n if n or n return n return fibonacci n fibonacci n This solution worked fine for smaller numbers n took secn took sec which is too long So next I was asked to optimize this Ideal Solution Using Dynamic programming I am storing each value found in a dictionary so that the next it looks for fibonacci of that number it can just look up from value dict def fibonacci n value dict the first two values of fibonacci is always if n or n return n if fibonacci n is already calculated then return it from dict if value dict get n return value dict n else store it in dict and return next time it is called for else value dict n fibonacci n value dict fibonacci n value dict return value dict n print fibonacci What are decorators Write a decorator that logs the functions arguments Solution Decorator is any function that takes in another function and adds functionality to it without manipulating the function itself It does this by using a wrapper function def decorator func def wrapper args print Logging the parameter of func is args return func return wrapper decoratordef operation x y return x yoperation decorator is just a syntactic sugar it is equivalent to res decorator operation What GIL global interpreter lock How does it allow multi threading in python Solution GIL is a lock which makes sure python interpreter is held by only one thread at a time That means only one thread can be in a execution status at any point of time And this is why python is a single threaded programming language This was introduced to solve the reference count problem which is used by python for garbage collection Then how is multi threading module working in python you may ask Well this global interpreter lock applies only for CPU bound activities So if there is any code which affects or uses CPU it automatically starts acting as a single threaded But all the general programs can still work in a multi threaded fashion What is WSGI and UWSGI Solution Web server gateway interface as the name suggests it is a interface between the application itself and web server Django provides runserver for development server and for debugging but for production we use WSGI in combination of any web servers like nginx apache or even uwsgi server wsgi and uwsgi are both protocols and these work with web servers to serve good performance application in production So when client makes a request to django application the request is read by nginx or any web server Then nginx passes this request to the uwsgi service which intern passes it to concerned django app Can we write a custom queryset in dango How Solution Yes we can create a custom queryset by customizing Managers A Manager is the interface through which database query operations are provided to Django models Each model contains atleast one Manager We can override Managers base queryset by override Manager get queryset method class Employees models Model name models CharField max length location models CharField max length On running Employees objects all it will return all the employees in database Now if we want to customize this to return only the employees from Toronto location then below can be done using Manager class TorontoEmployeesManager models Manager def get queryset self return super get queryset filter location Toronto class Employees models Model name models CharField max length location models CharField max length objects models Manager toronto objects TorontoEmployeesManager Now Employees toronto objects all will return only the employees from Toronto location arr list range arr arr arr arr Is arr arr Solution No arr arr creates a new reference of arr and assigns it to arr whereas arr arr copies the content of arr and assigns it to new variable called arr arr arr arrarr arr arr append print arr print arr How to hide a class variable from getting accessed outside the class class Sample def init self a b self a a self b ba and b should be hidden from outside of class Solution class Sample def init self a b self a a using double underscore hides class variable self b b What are middlewares in Django How do you create custom middleware Answer Middleware is a low level plugin that can be used to hook into Django s request response cycle There are already middlewares available by default when a django project is created and it can found in settings py We can create a custom middleware and include it in the list of middleware with the existing ones To create a custom middleware following structure needs to be followed Middleware class should always consist init and call class MyCustomMiddleware def init self get response self get response get response get response is the view which will be called after this middleware or its the next middleware in the list def call self request write the code to be executed before calling view here response self get response request pass the request to view and get the response back which will be returned write the code to be executed after calling view here return responseAdd this middleware into the Middleware section in settings py Also make sure the order of the middleware is correct Because it is called from top to down while processing requests and then bottom to up while returning response	2021-05-03 10:34:37
