Using break in a loop inside except* gives an error

[McAwesome123]

Environment data

• Pylance version: v2025.7.1
• OS and version: Windows 10 22H2
• Python version (& distribution if applicable, e.g. Anaconda): 3.12.4

Code Snippet

	except* TimeoutError as exc:
		x = 10
		while True:
			x -= 1
			if x < 0:
				break
			...

Expected behavior

The code works fine as far as I can tell, so this shouldn't be an error.

Actual behavior

Gives "break" is not allowed in an "except*" block

Thanks for the bug report. This is a bug in pyright, the type checker that pylance is built upon. A break statement isn't allowed directly within an except* block, but it is allowed if it's within a while or for loop, as it is in your code.

Could someone from the pylance team please transfer this bug report to the pyright project? Thanks!

This is fixed in 1.1.404
