Most Asked Python Interview Questions & Answers

Python is considered one of the easiest programming languages. It is widely used for web development, gaming applications, data analytics and visualization, and AI and machine learning. Since Python is used for multiple purposes, Python developers enjoy a massive market demand. 

If you plan to build a career in Python, you will have to prepare well for interviews. This blog has a list of the most commonly asked Python interview questions and answers.

Python Basic Questions for Freshers

Freshers are usually not asked too technical questions in the interview. The recruiter will ask you general questions about the Python language to know all theoretical concepts.

1. What is Python?

Python is an object-oriented programming language compatible with different platforms like Mac, Windows, Linux, Raspberry, etc. Python is an interpreted language which means we can execute Python codes immediately after writing them.

2. What are the benefits of using Python language?

• Python is a general-purpose programming language with a simple syntax. It enhances the readability of the code.
• Since Python is an interpreted language, we can execute the instructions directly without compiling the code.
• Another significant benefit of Python is that it is an open-source platform that anyone can freely download.
• Moreover, the built-in data structures in Python like a dictionary, list, and tuple enhance code readability.

3. What are the different scopes in Python?

There are four different scope types in Python: local, global, module-level, and the outermost scope. The first one has local objects within it that are being used at the moment. The global scope has objects that can be accessed anytime during the code execution. The global objects in the current module come within the module-level scope. Lastly, outermost scope refers to all the built-in objects that can be called during the program.

4. What is the meaning of break, continue and pass in Python?

We use the break statement in Python to terminate the loop or exit from it. The statements after the break get the control. However, the continue statement in Python enables the continuation or execution of the next iterations. The pass statement is used when we do not want any command or code to be executed. It adds a statement for the syntax purpose but does not execute it.

5. What are the keywords in Python?

The reserved words in Python like functions, identifiers, or variables are termed as keywords. They are essential for maintaining the syntax of the programming language. Python 3.7 version has 33 keywords, including none, true, and class, continue, def, return, lambda, pass, etc.

6. Explain the difference between lists and tuples.

Both lists and tuples are a class of data structure in Python. Lists are used to store different data sets simultaneously. Similar to the arrays, the list is declared in a different language. These are dynamic. On the other hand, tuples also comprise data types separated by commas. They are static.
