Top Python Interview Questions 2023

Decorators are a powerful feature in Python, allowing you to modify the behavior of functions or classes in a clean and efficient manner. Interviewers ask this question to assess your knowledge of Python’s advanced features and to understand if you can effectively use them to optimize code. By providing a practical use case, you demonstrate your experience in applying decorators to real-world situations, showcasing your problem-solving skills and mastery of the language.

As the method to call is determined at runtime, as shown in the above code, this is called runtime polymorphism. Then multiple units of car are created based on that template. OOPs, or Object-Oriented Programming is a programming model or paradigm which revolves around the concept of “OBJECTS”. Objects can be considered as real-world instances of entities like class, that contain some characteristics and behaviors specified in the class template. Following are some examples of functional programming in Python.

What is the difference between xrange and range functions?

You can accordingly curate the mid-level Python questions and answers according to the profile against which you are hiring. A mid-level Python developer will have some amount of experience and practical exposure to Python and its modules in python. The answer to this Python developer interview question can be modified depending on your project requirement.

• Compile-time polymorphism and Run time polymorphism are the two types of polymorphisms in OOPs languages.
• A Python module is a collection of Python commands and definitions in a single file.
• We will start off by taking an input and store it in ‘n’ and make a duplicate of it in ‘temp’.
• This helps me narrow down the potential causes and focus my efforts effectively.

It processes requests, updates the Model accordingly, and determines which View should be displayed based on the current state of the application. Another significant difference is the handling of strings and Unicode characters. In Python 2, there are separate string types for ASCII (str) and Unicode (unicode). In contrast, Python 3 has a single string type that supports Unicode by default, making it easier to work with international character sets.

Q68. What is monkey patching in Python?

Version control is essential for efficient software development, particularly when collaborating with others. It helps to keep track of changes made to the codebase, prevent unintentional overwriting of others’ work, and enables easy rollback to previous versions if needed. Type checking is an important part of any programming language which is about ensuring minimum type errors. The type defined for variables are checked either at compile-time or run-time.

Before going through the questions, here’s a quick video to help you refresh your memory on Python. Two different data frames can be stacked either horizontally or vertically by the concat(), append(), and join() functions in pandas. A pandas dataframe is a data structure how to become a python developer in pandas that is mutable. Pandas have support for heterogeneous data which is arranged across two axes. Keywords in Python are reserved words that are used as identifiers, function names, or variable names. They help define the structure and syntax of the language.
