How do you guys deal with ChatGPT constantly cutting off mid-code for longer Python scripts?

Question

I've been trying to build a custom script for some game automation, and my file is getting to about 500 lines. Every time I paste the code into ChatGPT and ask for a fix, it either hits a limit and stops halfway through or hallucinates parts of the logic it already saw. I tried typing 'continue' but the formatting usually breaks and the indentation goes haywire. Is there a better way to prompt it or a specific structure I should use to keep it from losing context on larger projects?

Modularize your code or use "stubbing"

Honestly, I feel your pain. Once you hit that 300-500 line mark, ChatGPT starts to lose the plot. The best way I’ve found to handle this—and it’s actually a good coding habit anyway—is to break your script into multiple modules. Instead of one massive script, try splitting your game automation into separate files like logic.py, input_handler.py, and main.py. When you need help, you only paste the specific function or class you’re working on. It keeps the "context window" clean and prevents those annoying cutoffs.

The "Function Signature" trick

If you absolutely have to work within one big file, don’t paste the whole thing. I usually provide ChatGPT with the function signatures of the rest of my code so it knows what’s available, but I only paste the actual body of the code I need fixed. You can say something like:

"I have a script with these functions: [list function names and parameters]. Please refactor ONLY the following function: [paste specific function]."

Tips for when it still cuts off

We’ve all been there where it just stops mid-sentence. If "continue" is messing up your indentation, here are a few things that worked for me:

• Prompt for blocks: Instead of asking for the whole script, ask it to "Provide only the updated process_data function." Smaller chunks rarely trigger the cutoff.
• Use the "Continue generating" button: If you're on the web interface, the actual button usually handles formatting better than typing "continue" manually.
• Request a Markdown Code Block: Explicitly tell it, "If you reach the limit, stop at the end of a complete function, and I will ask for the next one."

Check out an AI-integrated IDE

If you're doing this a lot, you might want to look into Cursor or the GitHub Copilot extension for VS Code. Because these tools "index" your whole folder, they have a much better sense of context than the ChatGPT web chat. You can just highlight a block of code and ask for a fix, and it won't hallucinate your other functions because it can actually see the rest of your files in the background.

Good luck with the game bot! Automation scripts can get messy fast, so keeping things modular is definitely your best bet for keeping the AI (and yourself) sane.
