3. 08:Functions
A function is a block of code which only runs when it is called.
You can pass data, known as parameters, into a function.
A function can return data as a result.

4. 09:Introduction to Modules
Nowadays, the Python programming language becomes one of the most popular
languages. When we write the codes for Production level Data Science
Projects, what happens is that our Python code grows in size, and as a result
most probably it becomes unorganized over time. So, keeping your code in
the same file as it grows makes your code difficult to maintain and debug.

5. 09:What are Python Modules?
 In Python, Modules are simply files with the “.py” extension containing Python
code that can be imported inside another Python Program.
In simple terms, we can consider a module to be the same as a code library or a file
that contains a set of functions that you want to include in your application.
 With the help of modules, we can organize related functions, classes, or any
code block in the same file. So, It is considered a best practice while writing
bigger codes for production-level projects in Data Science is to split the large
Python code blocks into modules containing up to 300–400 lines of code.

6. 09:What are Python Modules?
One advantage of functions is the way they separate blocks of code from your
main program. By using descriptive names for your functions, your main
program will be much easier to follow. You can go a step further by storing
your functions in a separate file called a module and then importing that
module into your main program. An import statement tells Python to make
the code in a module available in the currently running program file. Storing
your functions in a separate file allows you to hide the details of your
program’s code and focus on its higher-level logic. It also allows you to reuse
functions in many different programs. When you store your functions in
separate files, you can share those files with other programmers without
having to share your entire program. Knowing how to import functions also
allows you to use libraries of functions that other programmers have written.

8. 09:What are Python Modules?
The module contains the following components:
 Definitions and implementation of classes,
 Variables, and
 Functions that can be used inside another program.
