Frequently Asked Python Interview Questions

To help you prepare for interviews, here are some frequently asked Python questions and their answers:

What is the difference between lists and tuples in Python?

Lists and tuples are both collection data types. However, lists are mutable, meaning they can be changed, while tuples are immutable and cannot. Use lists when you need a collection that might change, and tuples for fixed data.

How do you manage exceptions in Python?

Exception handling in Python is conducted using try-except blocks. Ensure you specify the exception type you anticipate and gracefully handle it, keeping your program robust and error-free.

What is wxPython, and how is it used?

wxPython is a GUI toolkit for Python, allowing developers to create applications with a native look and feel. It's particularly useful for creating desktop applications, including functionalities like dropdown menus and setting directory paths with set directory path wxPython.

How do you optimize Python code for better performance?

Optimize Python code by using efficient algorithms, minimizing the use of global variables, leveraging built-in functions, and employing the least complex data structures suitable for your task.
