Python, one of the most popular programming languages, is used not only by software developers but also by data analysts, accountants and scientists. This beginner-friendly language can be used across platforms and has many applications that can save businesses both time and effort. It is a multi-purpose programming language that has been in use for over the past 20 years, and today it is especially creating waves in the area of automation. Top companies are rampantly hiring Python developers, who are offered highly lucrative pay packages.
If you want to hire highly knowledgeable Python developers, then you must focus on the type of Python programming questions to ask during the assessment tests and interview. You can make use of automated online assessment platforms to include these questions and also assess coding abilities. These platforms reveal many facets of a candidate’s technical competencies in a few simple steps. A few of the popular questions that are usually asked while hiring for artificial intelligence, machine learning, data analysis, scientific research and more are discussed in the next section.
Top Python Interview Questions and Answers
Q1. What are the applications or uses of Python?
Ans: Python is a general-purpose programming language that can also be used for web development, AI, ML, Data analysis and visualisation and scripting for simple automation.
Q2. How is memory managed in Python?
Ans: Python private heap space is used for memory management and is divided into stack memory and heap memory. References are created in stack and objects are created in heap memory. The python interpreter manages all the objects and data structures that developers do not have access to. It also has a garbage collector feature that removes dead objects from memory.
Q3. Is Python a compiled or interpreted language?
Ans: Python is compiled and an interpreted language. To explain in detail, source code is first compiled to give a byte code which is later interpreted using the machine language by a virtual machine.
Q4.What is PEP 8?
Ans: Python Enhancement Proposal or PEP is a style guide that is widely used as the standard format for improved readability of Python code. It is a document that helps you understand the best indentation levels, line lengths, tabs and spaces, etc. that you need to use.
Q5. What is the significance of NameSpace in Python?
Ans: It is a naming system which ensures that each object has a unique name and also facilitates the reuse of a name, especially while writing long programs.
Q6. What is PYTHONPATH?
Ans: PYTHONPATH is an environment variable that is used by Python Interpreter to check the presence of new imported modules in directories and to determine which to load.
Q7. What are python modules? Name some commonly used built-in modules in Python?
Ans: Python modules are .py files that contain executable Python code that may be functions, classes or variables.
Q8. What are global variables and local variables?
Ans: Global variables are declared outside a function or in global space and can be assessed either inside or outside a function. The variables declared inside a function are called local variables, and they are present in the local space.
Q9. What makes range and xrange in Python different?
Ans: xrange and range provide a way to generate a list of integers for your requirements. While range returns a Python list object, xrange returns an x range object which makes it ideal for generating a wide range of list.

FAQ
FAQ
1. What is Python?
Python is a high-level, interpreted, general-purpose programming language. Being a general-purpose language, it can be used to build almost any type of application with the right tools/libraries. Additionally, python supports objects, modules, threads, exception-handling, and automatic memory management which help in modelling real-world problems and building applications to solve these problems.
2. What is Scope in Python?
Every object in Python functions within a scope. A scope is a block of code where an object in Python remains relevant. Namespaces uniquely identify all the objects inside a program. However, these namespaces also have a scope defined for them where you could use their objects without any prefix.
3. What are the key features of Python?
These are some of the essential tools that we should have
- Interpreted Language
- Dynamically Typed
