# 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 as your language to start programming, you've made an excellent choice! 🙂

Python has relatively concise code compared to other programming languages, requiring fewer lines to accomplish the same functionalities.

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 Programs`: You can create programs to automate tasks such as 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`: Develop a web server that serves as the brain of interactive online services.

<br />

## Coding Practice

To learn programming quickly, you should frequently write code.

Type `average = sum(numbers) / len(numbers)` into the practice code editor.

- *sum*: Python function to calculate the sum of numbers enclosed in the parentheses

- *len*: Python function to determine the length of the data within the parentheses

The code you input calculates the average of the numbers stored in the variable `numbers` and saves the result in the variable `average`.

Python is very popular due to its concise code and broad use in data analysis, artificial intelligence, automation, web development, and more. It is also a suitable language for programming beginners.
