Q2. 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. Differentiate Between Instance and Class Variables?

The difference between instance and class variable is as follows:
