Python is a high-level programming language that has become increasingly popular in recent years, especially in the field of data science and machine learning. If you’re a fresher looking to get into Python programming, you’ll need to prepare for potential interview questions to land your dream job. In this blog, we’ll go over the top 20 Python interview questions and their answers to help you prepare.
Python is a high-level, interpreted programming language used for web development, data analysis, artificial intelligence, and other applications.
Python is easy to learn and understand, has a vast library of modules and functions, has high-level built-in data structures, and is an open-source language with a large developer community.
Python has several data types, including integers, floating-point numbers, strings, Booleans, and complex numbers.
PEP 8 is a set of guidelines for Python code style and formatting that make code more readable and consistent across different projects.
Lists and tuples are both types of sequences in Python, but lists are mutable, while tuples are immutable. This means you can modify a list by adding, removing, or changing elements, but you cannot modify a tuple after it is created.
A dictionary is a collection of key-value pairs in Python. It is similar to a hash table or associative array in other programming languages.
A lambda function is an anonymous function in Python that can take any number of arguments, but can only have one expression.
‘==’ is used to compare the values of two objects in Python, while ‘is’ is used to compare the identities of two objects.
A module is a file containing Python definitions and statements. It can be used to organize code and make it reusable across different programs.
Pip is a package manager for Python that is used to install, upgrade, and uninstall Python packages.
The in it method is a special method in Python classes that is called when an object is created. It is used to initialize the attributes of the object.
Object-oriented programming is a programming paradigm that focuses on creating objects that contain both data and methods to manipulate that data.
A class is a blueprint for creating objects, while an object is an instance of a class.
A decorator is a function that takes another function as an argument and adds functionality to it without changing the function itself.
The str method is a special method in Python classes that is called when the object is printed using the print() function. It is used to return a string representation of the object.
Recursion is a technique in programming where a function calls itself to solve a problem. It is often used to solve problems that can be broken down into smaller subproblems.
A generator is a special type of iterator in Python that generates a sequence of values on the fly, rather than storing them in memory.
Self is used to represent the instance of the class. With this keyword, you can access the attributes and methods of the class in python. It binds the attributes with the given arguments. self is used in different places and often thought to be a keyword. But unlike in C++, self is not a keyword in Python.
Unit test is a unit testing framework of Python.
Unit testing means testing different components of software separately. Can you think about why unit testing is important? Imagine a scenario, you are building software that uses three components namely A, B, and C. Now, suppose your software breaks at a point time. How will you find which component was responsible for breaking the software? Maybe it was component A that failed, which in turn failed component B, and this actually failed the software. There can be many such combinations.
This is why it is necessary to test each and every component properly so that we know which component might be highly responsible for the failure of the software.
In conclusion, if you are a fresher preparing for a Python interview, it is important to have a good understanding of the basics of Python programming language. Practice coding, work on small projects, and review common interview questions to help build your confidence and enhance your problem-solving skills. Some companies like Solitaire infosys also provide industrial training in many languages including python. It is one of the best python training provider in Chandigarh. They provide both 6 week and 6 month industrial training in Chandigarh.
In this blog, we have covered the top 20 Python interview questions that are frequently asked in Python job interviews for freshers. These questions cover a wide range of topics such as data types, control flow, object-oriented programming, and more. By understanding and practicing these questions, you can increase your chances of performing well in a Python job interview.
Remember that while technical knowledge is important, interviewers are also interested in your communication skills, problem-solving ability, and your ability to work in a team. So, be confident, be well prepared, and show your passion for programming during the interview.
