I'm new to coding and using ChatGPT as my guide. I'm trying to work on an image of a pool table and some balls in Python. I can successfully display the image with my code, but whenever I try to make changes and add new lines, both the original and the modified images show up.
I'm confused – does every line of code execute when I hit 'run'? ChatGPT mentioned I can press Ctrl + Enter to run just one line, but that doesn't seem to work for me. For example, if I use print(hello) and then print(goodbye), running the script prints both 'hello' and 'goodbye'.
I'd really appreciate any help with this because I've wanted to learn Python for a long time!

You shouldn't rely solely on ChatGPT for learning programming. There are tons of free resources available, like tutorials, videos, and documentation online. They offer structured paths for learning Python and might help clarify concepts better. Experimenting with code is great, but understanding the flow of execution really matters too. Take one step at a time and don't hesitate to make mistakes; that's part of the learning process!
It sounds like you might be running your entire script instead of just the line you're trying to execute. Make sure you're using the right environment where you can select specific lines to run. If you're using something like Jupyter Notebook or an IDE that allows for running cells or lines, Ctrl + Enter should work. Also, remember that when you run a script, it starts from the top down, running all lines unless you conditionally skip some with an if statement or similar. If you need to debug, inserting print statements can help you understand what's happening at each step!
I appreciate the suggestion! I'm just trying to find a method that clicks for me. Maybe I should explore some online courses that walk through the basics step-by-step.
