Infinite Run Python

[signal verge]

I'm resolving a question at my course what I have to do a QR Code Generator at Python.
The library "qrcode" was downloaded and imported at my code, but the code is running infinitely and I'm not able to solve it. What I do to solve this problem?

Running infinitely? Is that all the code you have?

[signal verge]

Yes, is just this

I run the code and it doesn´t finish executing

[trail apex]

import qrcode

img = qrcode.make("https://www.youtube.com/watch?v=5lu55jOOU7g")
img.save("qrcode.png")

@viscid cliff why would that hang? Permission issue? Maybe something more out of the box…

If your script is hanging, it's usually due to missing dependencies or an environment issue. Here's a quick guide to help you troubleshoot:

If the qrcode library hangs, it is typically due to missing image processing backends or environment-specific I/O blocking.

1. Verify Dependencies

The qrcode library requires Pillow to generate image files. Ensure you have installed the library with the necessary extras:

pip install "qrcode[pil]"

2. Isolate the Issue

Create a minimal script to determine if the hang occurs during image generation or during file I/O:

import qrcode

# Test generation without I/O
try:
    qr = qrcode.QRCode()
    qr.add_data("test")
    img = qr.make_image()
    print("Generation successful")
except Exception as e:
    print(f"Error: {e}")

3. Troubleshooting Checklist

• File Permissions: If the hang occurs during img.save('file.png'), verify that the script has write access to the target directory.
• Headless Environments: If running on a server, ensure you are not calling img.show(), which will hang waiting for a display that doesn't exist.
• Blocking I/O: Ensure you aren't performing heavy image processing in a main event loop if you're using a web framework.

Let me know if that helps or if you're still seeing the hang!
