Introduction
Python is a high-level, interpreted programming language known for its simplicity, readability, and versatility. It
was created by Guido van Rossum and first released in 1991. Python is widely used in various fields, including
web development, data science, machine learning, automation, and more. Python supports multiple
programming paradigms, including object-oriented, procedural, and functional programming.

Q2. Is Python a compiled language or an interpreted
language?
Python is an interpreted language, which means that the code is executed line by line, directly by the Python
interpreter, without the need for a separate compilation step. The Python interpreter reads the source code and
translates it into intermediate bytecode, which is then executed by the Python Virtual Machine (PVM).

Q3. What does the '#' Symbol in Python?
The '#' symbol in Python is used to start a comment. Anything written after the '#' symbol on the same line is
considered a comment and is ignored by the Python interpreter. Comments are used to add explanatory notes,
reminders, or documentation to the code, making it easier for other developers to understand the code's logic.

Q7. What are modules in Python?
In Python, modules are files that contain Python code and are used to group related functions, classes, and
variables together. A module can be imported into other Python programs using the `import` statement. By
using modules, developers can organize their code more efficiently and reuse functionalities across multiple
programs.

Q8. What are packages in Python?
In Python, packages are a way of organizing related modules in a hierarchical manner. A package is
essentially a directory containing a special file named `__init__.py`, which makes Python treat the directory as
a package. Packages allow developers to create a more organized structure for their code by grouping related
modules together. They help prevent naming conflicts and provide a better way to manage code in large
projects.

`NameError`
`TypeError`
`IndexError`
`KeyError`
`ValueError`
`FileNotFoundError`

Q10. What are decorators in Python?
Decorators in Python are a powerful feature that allows developers to modify the behavior of functions or
methods without changing their actual code. Decorators are applied to functions using the `@decorator_name`
syntax before the function definition. They are often used to add functionality such as logging, caching, or
authorization to functions, making code more modular and reusable.
