In this era of digitalization, the job of a Python specialist has become one of the most lucrative jobs. In recent days, many companies are hiring for the post. Along with the small companies, large companies like Google, Amazon, and Microsoft also have job opportunities for Python specialists. So, the job options for Python developers are many. Therefore, it has become important for the tech experts to get ready for the interview.
If you are skilled enough to handle the technical details of programming, you can apply for the job. But a complete knowledge of Python is also needed. Without that, you may fall behind the other competitors. Well, you cannot expect the interview for the Python expert to be like the regular interviews for tech experts posts. And, the Python interview questions are also different from the usual questions asked for a web developer job.
Here, in this article, we will discuss the details of the Python interview. I hope it will help you to succeed in the interview easily. So, straighten your back, pick up your pen and paper and focus! You will get some essential details that you need the most right now.
What is Python?
Before we delve into the details of the interview questions, we first must get an idea of what Python is. Many of you may have heard the term “python,” but few of you have an idea about what it actually is. So, let us tell you what it is. Python is an advanced programming language used for building almost all types of applications. Moreover, Python supports different objects, modules, threads, and automatic memory management and helps address real-time problems.
The open-source language is designed for scripting. Its simple syntax improves the readability and thus lowers down the cost of program maintenance. It supports various third-party packages. The high-level data structures of Python are combined with dynamic typing and binding. Thus, it can attract a vast community of developers to develop and deploy rapid applications.
Now, let’s focus on the vital Python interview questions that you may have been asked.
- Is Python a dynamically typed language?
Type-checking is a process in programming languages. A dynamically typed language performs the type checking for the data during execution. As Python executes each statement line by line, it also performs the type-checking process simultaneously. So, yes, Python is a dynamically-typed language.
- Is Python an interpreted language?
Yes, of course, Python is an interpreted language. It executes all statements line-by-line as an interpreted language does. Other examples of interpreted languages are Python, JavaScript, R, PHP, and Ruby, etc.
- What is PEP 8?
It is one of the most significant Python interview questions. The full form of PEP is Python Enhancement Proposal. It is an official design document that provides information to the Python community. Also, it describes new features for the Python program or its processes. The benefit of PEP 8 is that it works as a document for the style guidelines for Python code.
- How is the memory management process in Python?
To perform this task, Python has its very own Python Memory Manager. The manager allocates the memory as a private heap space dedicated to Python. All of the Python objects are gathered in this heap. And the programmer cannot access it as it is private. Moreover, Python has an in-built garbage collection facility. It helps to recycle the unused memory to the private heap space.
- Define what the Python namespaces are.
Python namespaces include local namespaces, global namespaces, built-in namespaces, and so on. Local namespaces are the section for local names, whereas global namespace includes the names of the imported packages and modules used in the current project.
- Do you know about the scope in Python?
When namespace usually identifies all of the objects within a Python program, a scope is a block of code to keep an object relevant in Python. The various scopes are local scopes, global scopes, module-level scopes, outermost scope and so on.
Well, if you prepare for Python interview Questions, you must be ready for some advanced-level questions. One of such questions is what the scope resolution in Python is. Scope resolution is a process that works in Python for the objects sharing the same scopes and same names but different functions.
Python Interview Questions: The Add-ons
Although you prepare all of the questions well, you may not get a chance to enter the profession of Python experts because multiple applicants are sitting beside you with more advanced knowledge. So, to stay ahead in the competition, you must know some more.
- Learn how to write code on a whiteboard or paper
- Learn the basic Python control flow
- Be ready to discuss how you used Python
- Learn how to use list comprehensions
- Get an idea about the use of generators
- Learn the basics of OOP or Object-Oriented Programming
Final Words
So, these are some of the essential questions and tips that will help you stay a cut above the rest in a Python interview. We hope now you have got an idea about how to prepare for the Python interviews.
