1. Go to the official Python website: https://www.python.org/downloads/
2. Download the latest version of Python for your operating system (Windows, Mac, or Linux).
3. During installation, check the box that says "Add Python to PATH" (this makes it easier to run Python from the command line).

Verify your installation by opening a terminal or command prompt and typing:python --version

Getting Started with Python

Setting up Your Environment

1. Create a folder for your Python projects using these commands:
1. mkdir python-projects
2. cd python-projects
2. Create a new file for your script:
1. touch my_first_script.py
3. Install a text editior like:
1. VS Code
2. Sublime Text

Writing Your First Script

Writing a Script

1. Open my_first_script.py in your text editor.
2. Add the following code:
1. print("Hello, World!")
3. Save the file.

Writing Your First Script

Running the Script

1. Open a terminal or command prompt.
2. Navigate to your project folder:
1. cd path/to/python-projects
3. Run the script:
1. python my_first_script.py
4. You should see the output:
1. Hello, World

Enhancing Your Script

Add Variables and User Input

1. Update your script to include variables and user input:
1. name = input("What's your name? ")
2. print(f"Hello, {name}! Welcome to Python."
2. Run the script and interact with it.

+ Activity 2

Enhancing Your Script

Add a Loop

1. Modify your script to include a loop:
1. times = int(input("How many times should I greet you? "))
2. for i in range(times):

print(f"Hello, {name}! (Time {i+1})") 2. Run the script and see the loop in action.

+ Activity 3

Enhancing Your Script

Add a Function

1. Add a function to make your script more modular:
1. def greet_user(name, times):

for i in range(times): print(f"Hello, {name}! (Time {i+1})") b. name = input("What's your name? ") times = int(input("How many times should I greet you? ")) greet_user(name, times) 2. Run the script and observe how the function works.
