# Assign a list of numbers to the variable 'numbers'
numbers = [10, 20, 30, 40, 50]

average = "?"

print("Average of the numbers:", average)


# Define a function with the 'def' keyword
def add(a, b):     # Name the function 'add'
    return a + b   # Return the sum of 'a' and 'b'

# When 3 and 5 are passed to the add function, 3 is assigned to 'a' and 5 to 'b'
# Assign the return value of the add function, 8, to the variable 'result'
result = add(3, 5)

print('Value of add(3, 5):', result)
# Output 8

# Reasons Why Python is Popular

If you've chosen Python to begin your programming journey, you've made a great choice!

Python has a compact, readable syntax that requires fewer lines of code to achieve the same functionality as other languages.

It is also utilized across various fields like data analysis, artificial intelligence, automation, and web development, making it broadly adopted in many industries.

<br />

## What can you create with Python?

- `Office Automation`: Automate tasks like processing Excel data, merging PDF files, and generating Word documents.

- `AI Models`: Train and utilize AI models for specific areas such as image classification, natural language processing, and speech recognition.

- `Web Servers`: Build the backend for interactive web services and applications.

<br />

## Coding Practice

The best way to learn programming is by writing code regularly.

Try typing `average = sum(numbers) / len(numbers)` into the practice editor.

- *sum*: A Python function that calculates the total of the numbers inside the parentheses

- *len*: A Python function that returns the number of items in the data inside the parentheses

This code calculates the average of the values in `numbers` and stores the result in the variable `average`.

Python is widely recognized for its popularity, thanks to its concise syntax and versatility across fields like data analysis, artificial intelligence, automation, web development, and more. Additionally, it serves as an excellent choice for programming beginners.
