Python Interview Questions For Freshers
Working as a Python seems fun and interesting but cracking an interview can be a tough job because of the many types of questions that the interviewers can ask. But not to worry, as we have prepared some Python interview questions and answers to make you ready for your dream work.
What Is Python?
If you are a fresher, then the first question that the interviewer can ask is about Python. So, you can start like Python is a high-level programming general-purpose programming language. It is an open source that emphasizes code readability and provides easy-to-use syntax. This language was first introduced in 1991 by Guido Van Rossum, who stepped down as a leader in 2018.
After answering this question, the interviewer can also ask the type of language Python is. And he or she might do this to test you and to know how much you know about Python. And to help you, we have mentioned some more Python basic interview questions that can be asked in your interview.
What Are The Applications Of Python?
Python is known for its general purpose, and it can be practically used in any software development sector. Due to its versatility, it can easily be used to create web applications, desktop GUI applications, and console-based applications. Additionally, it is widely used in software development, scientific and numeric analysis in artificial intelligence and machine learning. And to build a business application is not an easy task as they are different from standard apps, and Python is the perfect choice to build them. Besides, Python can create audio and video-based applications, 3-D CAD, enterprise applications, and image processing applications.
If you want to learn all the applications to grab your dream job, then several online platforms are available. And one of the trending online academies is AttainU which provides a full course on Python. AttainU also offers you placement in tech companies and guides you for the Python interview questions so that you can easily crack your job interview.
What Are The Features Of Python?
- Interpreted: Python is highly interpreted, which means, unlike other languages like C and its variants, Python doesn’t need to compile before it is run. It allows you to write code in a readable language, and you can run those codes directly from the interface. Other languages need PHP and Ruby to compile and run the codes.
- Dynamic: Python is dynamic, as you don’t need to add the type of variables like you need to mention in other languages. You just need to write codes like x = 111 or x = “hello world,” and it will automatically declare variables as strings or booleans without any error.
- One can write Python code quickly: Running Python code can be slower as compared to other languages like C., But you can write Python code quickly due to the inclusion of a C-based extension which can be optimized there and then.
- Object-oriented programming: Python is object-oriented as it allows the definition of classes along with composition and inheritance.
- Use in many areas: It is very flexible as you can use this language in web applications, scientific modeling, big data applications, and automation. It is also often used as a “glue” code to get other languages and components to play.
Python Technical Interview Questions
Apart from basic Python interview questions, some technical questions can also be asked which are listed below.
What Is PEP 8?
This is the most common question included in Python coding questions and is also a very important element for programming in Python. PEP or Python Enhancement Proposal is an acronym that explains new features suggested for the programmers and detailed elements for the communities, such as design and style. PEP 8, often known as PEP8 or PEP-8, is the document that outlines the best elements and recommendations for writing Python code.
What Is Python Path?
Python path is an environmental variable to add additional directories or user-defined modules so that they can be directly imported into a Python program. You can use the sys. Path directory list to set before running the Python interpreter.
What Are Flask And How Its Benefits?
Flask is a web framework that allows you to build web applications providing tools, technologies, and libraries. It integrates unit testing support and provides a built-in development server and fast debugger. Restful request dispatching, Unicode base, and support for cookies are the additional benefits of the flask.
What Is The Difference Between A List And A Tuple In Python?
The key difference between a list and a tuple is that a list is mutable, which means one can change or modify the value under the list. On the other hand, tuples are immutable as you cannot change or modify them according to your choice.
What Is Pass In Python?
Pass is the statement given to a specific code that you don’t want to be executed when you run the program.
What Are Sets in Python?
Set is a built-in data type in Python that is used to store multiple data in a single variable. The data in sets are unorganized, unchangeable, and unindexed.
What Function Do In Python?
This is the Python programming questions that are mostly skipped by the developer and asked most of the time in an interview. A function is a block of data that can only run when it is called and can be stored for feature use. In Python, you can define any function using “def” attributes in a simpler way, as given below.
def my function ():
print(“hello from a function”)
What Are Comments In Python? How Can You Mention Them?
Comments in Python are the line that suggests the compilers and the interpreters ignore the code that you don’t want to execute. You can comment on any line by hash # that will turn into a green color, suggesting the code will not be executed.
Python Interview Questions For Experienced
Even experienced developers switch the company for better salary, and for that, they need to face an interview. To crack the Python interview questions, we have suggested some of the questions that can be asked in the coding interview.
Does Python Support Multiple Inheritance? If Yes, How.
Multiple inheritances mean the class can be driven by more than one parent class. This feature can be seen in Java but is unavailable in Python.
What Do You Do About Monkey Patching In Python?
Money patch is the term that refers to dynamic modifications of a class or module in Python at a run time. This can be among Python interview questions when you are experienced, or you want to switch from the company you are currently working for. If you want to prepare for the interview, you can prepare from attainu.com, which provides various programming languages.
Define Encapsulation In Python?
Encapsulation is the process where you need to bind the codes and the data together. And Python class in the example of encapsulation allows you to put your codes together.
How Can You Do Data Abstraction In Python?
Data abstraction is the feature that provides the required details and hides the implementation from the world. This process can be achieved from interfaces and abstract classes in Python. This question is often ignored by the students, and it is often asked in the Python viva questions.
What Are The Differences Between Django, Pyramid, And Flask?
- Flask: Flask is a ready-to-use framework that is primarily built for small applications with simpler requirements.
- Pyramid: The pyramid is built for larger applications where developers are flexible in using the right tools for their projects. They get the freedom to choose the database, URL structure, templates, style, and many more.
- Django: Django can also be used for large applications like a pyramid, and it includes an ORM. The developer needs to provide the model, the view, and the templates and map them to the URL that can be served to the user.
These are the most important elements used by the programmer and interviewers also included in the Python interview questions to test the developer’s knowledge.
How Is Python Numpy Better Than Python List?
Numpy and List both have a similar function when it comes to Python programming, but developers prefer to use Numpy as it is fast, convenient, and consumes less memory.
These are the Python interview questions that are mostly asked by the interviewer whether you are a fresher or working for years as a Python developer.
Python is the most demanding language in today’s time and easy to learn as compared to other languages like Java. C, C++, and many more. As this language has caught fire recently, there are very few Python developers. And many people don’t have an idea of the Python interview questions, and besides knowing all the skills, they fail to grab a job. With this consideration, we have mentioned all the important questions that can be asked by the interviewer. If you are interested in learning Python and want a decent job, then you can contact AttainU for the complete course and guidance.
