List is mutable while tuple is immutable.

• List can be modified while tuple cannot be modified.

• List is defined using square brackets [] while tuple is defined using parentheses ().

• List is used for homogenous data while tuple is used for heterogenous data.

• List is slower than tuple in terms of performance.

• Example of list: [1, 2, 3] and example of tuple: (1, 'hello', 3.14)

Reverse a string using recursion.

• Create a function that takes a string as input.

• Check if the string is empty or has only one character.

A decorator is a design pattern in object-oriented programming that allows behavior to be added to an individual object, dynamically.

• Decorators are used to modify the behavior of a function or class without changing its source code.

• They are implemented using the @ symbol in Python.

• Decorators can be used for logging, timing, caching, and more.

• An example of a decorator is the @staticmethod decorator in Python, which marks a method as static.

A .pyc file is a compiled Python file that contains bytecode.

• It is created by the Python interpreter when a .py file is imported or run.

• It is platform-independent and can be executed on any system with the same version of Python.

• It speeds up the execution of Python code as the interpreter does not have to compile the code every time it is run.

• It can be deleted without affecting the original .py file, as the interpreter will re-create it if necessary.
