Here’s what our simple greeting program will look like:

# This is a simple greeting program

# Ask the user for their name
name = input("What's your name? ")

# Print a greeting to the user
print("Hello, " + name + "! Nice to meet you.")

This program first asks the user for their name (the input() function in Python prints a prompt to the screen and waits for user input). It then prints a greeting that includes the user’s name.

Step 4: Save and Run Your Program
After you’ve typed this code into your Python file, save your changes. You can then run your program from the terminal by navigating to the directory where your file is saved and typing python greeting.py. You should see your prompt, be able to type your name, and receive a greeting.

Step 5: Debugging
If you made a typo or mistake and your program doesn’t run correctly, don’t worry! Debugging is a big part of programming. The error message will give you a clue about what went wrong so that you can fix it.

Step 6: Experiment and Learn
Now that you’ve written your first program, you can start to experiment. Maybe you want to ask the user for more information, or print different messages based on their input. The possibilities are endless, so keep exploring and learning!
