🔄 Real-World Example: Debugging with Gemini CLI

Let’s say you paste this Python traceback into Gemini CLI:

> Traceback (most recent call last):
>   File "script.py", line 2, in <module>
>     print(data["name"])
> NameError: name 'data' is not defined

Gemini CLI response:

The error indicates that data is not defined before it's being accessed.
Solution: Make sure data is initialized. Here's a possible fix:

python

data = {"name": "John"}
print(data["name"])

Time saved: Several minutes Googling and trial-and-error.
