Python Interview Questions
Does python have OOPs Concept ?
Python is an object-oriented Programming Language. This means that any program can be solved in python by creating a model However, Python can be heated. as a procedural as well as structural language.
What is split used for?
The split () method is used to separate a given string in python
a= "edureka python " print (a. split ())
How to import modules in python
Modules in python can be imported using the import keyword you can import modules in three ways
- Import array
- import array as arr
- form array import
How do you do Data abstraction in python?
Data abstraction is providing only the required details and hiding the implementation from the world. It can be achieved in python by using interface and abstract class
What is Polymorphism in python
Polymorphism in python means the ability to take multiple forms so far instance. If the parent class has a method named ABC then the child class also can have a method with the same name ABC having its own parameter and variable python allows polymorphism
Does python support multiple inheritances ?
multiple inheritances mean that a class can be derived from more than one parent class. Python does support multiple in heritance unlike java
How to create empty class in python ?
The empty class does not have any code defined within its block. It can be created using the pass keyword However, you can create an object of this class outside the class itself in python the passing comment does nothing when its executed as a null statement
Class a: pass obj= a() obj name= "xyz" Print ("Name =" obj.name)
What does an object() Do?
It returns a featureless object that is based on class for all classes. Also, it does not take any parameters.
Define encapsulation in pythons?
encapsulation means binding the cod and data together. A python class is an example of encapsulation.
What are built in types of python?
- Floating -point
- Complex number
- Built-in function
What are docstrings in python
Docstrings in Python are not actually comments, but they are documentation strings. These Docstrings are within triole quotes. They are not assigned to any variable and there fore at times, serve the purpose of comments as well.
" " " Usign docstrings as a comment " " " X=8 y=7 z= X*y Print (z)
What are generators in Python
Functions that return an iterable set of items are called generators.
What is pickling and Unpickling?
The pickle module accepts any Python object and converts it into a string representation and dumps it using the dump function this process is called pickling while the process of retrieving original Python objects from the stored string representation is called unpicking
What is other methods iterators
Iterators are objects which can be traversed through or iterated upon.
What is self in Python
Self is an instance or an object of a class. In python, this is explicitly included as the first parameter. This is not the case in java where it’s optional. It helps to differentiate between the methods and attributes of a class with local variables. The self variable in the lnit method refers to the newly created object. While in other methods, it refers to the object whose method was called.
What is Lambda Function?
An anonymous function is known as a lambda function. This function can have any number of parameters but have just one statement
a=lambda x,y:X+Y Print= (a(6+4));
What is _init_?
_init_ is a method of constructor in Python. This method is automatically called to allocate memory when a new object of a class is created. All classes have the _Init_ method
Class EMP: Def_Init_(Self, Name); Self.name=name E1= EMP["ram"] Print (E1.name)
What are function in Python
A function in Python is a block of code that is executed only when it is called. to define a python function the def Keyword is used
Is indentation required in Python
Indentation is necessary for python. It specifies a block of code. All code within loops classes functions etc within an indented block. It is usually done using four space characters. If your code is not indented necessarily. It will not execute accurately and will errors as well.
Is Python Case Sensitive ?
Yes, Python is a case-sensitive language.
What is Local and Global Variable In python
There are 2 types of variables Local and Global Variable In python
Global Variables:- Variables declared outside a function or in a global space are called global variables. This variable can be accessed by any Function in the program.
Any variable declared inside a function is known as a local variable. This variable is present in the local and not in the global space
What are python modules? Name somecommonly used built-in modules in python?
Ans:- Python modules are files containing python code. These can be function classes or variables. A python module is a .py file containing executable code.
Some of the commonly used built-in modules are
- data time
What is namespace in Python?
A namespace in Python is the naming system used to make sure that names are unique to avoid naming conflicts.
How is memory managed in Python
1. Memory managed in python is managed by python private heap space. All python objects and data structures are located in a private heap programmer does not have access to this private heap. The python interpreter takes care of this instead.
2. The allocation of heap space for Python objects is done by python’s memory monayerThe core API gives access to some tools for the programmer to code
3. Python also has an in-built garbage collector which recycles all the unused memory so that it can be made available to the heap space.
What is pep8?
The name PEP8 stands for Python Enhancement Proposal. It is a set of rules that specify how to format Python code for maximum readability.
How is python an interpreted language ?
An interpreted language is any programming language that is not in machine-level code before runtime. Therefore, Python is an interpreted language
What type of language is python? Programming or scripting?
Python is capable of scripting but in the general purpose programming language
Is Python easy to learn, and where can I start learning it?
Well it is a very subjective question. It really depends on person to person, about how much they are ready to put into it, how much energy they are putting into it. According to my perspective I will consider it moderate. Initially everything seems easy, but the resistance comes in when you have to use multiple functions for complex problems.
I started by getting comfortable with the syntax which is said to be easier compared to other programming language because it’s syntax resembles very much to the English language with proper grammar just like SQL. I used Jupyter notebooks initially and then moved to another IDE named Spyder.
After learning basic functions I moved towards the libraries such as NumPy, Pandas , Seaborn , Scipy etc. I am still in the learning phase of it because you never really stop learning when it comes to programming and data science. There are daily updates be it libraries, functions, algorithms etc.
Can I start learning Python even if I don’t have any experience in programming?
Yes, Why not?
It is even better to start your programming journey with python.
Learning a programming language doesn’t sound as exciting as a breakdance competition on an aircraft carrier. The use of white space and common expressions has eliminated the need for tedious variable declarations and unattractive curly brackets.
Python also requires less code to complete basic tasks, making it an economical language to learn. Python code is often 3-5 times shorter than Java, and 5-10 times shorter than C++.
The most beautiful thing that I personally like about python is its Indentation Technique instead of commas, brackets and this unique feature makes it quite easy and simple to learn
