Advanced Python Interview Questions and Answers
Q1: If a function doesn’t have a return statement, is it valid?
Yes, it is valid. By default, all the functions in Python return the particular value “None” unless an explicit return statement is present to return a value that’s not “None”.

Q2: What’s the main difference between local and global namespaces?
The main difference is that the creation of Global namespaces occurs when the program begins, while local namespaces are created within a function when that function is called.
Q3: Differentiate between exception handling in Python and Java.
In Java, we can do exceptional handling using these five keywords: try, catch, throw, throws, and finally. On the other hand, Python has its own method for exception handling, and we can use the block <try-except> to handle exceptions. The <try-except> block can help you check error details without program termination and may also offer suggestions for fixing the error.

Q4: Describe compile-time and run-time code checking in Python.
Compile-time and run-time code checking is done uniquely in Python and involves first checking a small portion during compile-time checking. Then most other checks like name and type checks happen only during code execution. So referencing a non-existent function in your Python code will still lead it to successful compilation. But your code will fail with an exception only during code execution when the code execution path references the non-existent function.

Q3. What are the applications of Python?
Python has several applications, including business, scientific, numeric, web, audio/video-based, software development, desktop GUI, console-based, and 3D CAD applications.
Q4. What are the advantages of Python?
Python has English-like syntax, is concise, object-oriented, high-level, interpreted, free, and open source. Hence, Python is easy to learn, access, and write code in. Also, Python code is more readable, portable, and maintainable, and Python offers vast library support. No wonder then that Python improves the productivity of software developers and makes the process of software development smoother.
Q5. How many data types are there in Python?
Python has five standard data types: String, Numbers, Tuple, List, and Dictionary.
