Pull request overview
This PR implements security improvements to the Python setup script by replacing assertions with proper exception handling and adding validation for the assembler tool path to prevent potential security vulnerabilities.
Changes:
- Replaced assert statements with explicit exception raising for better error handling
- Added assembler tool path validation to prevent execution of untrusted tools
- Converted list comprehension to explicit loop for assembler compilation with shell=False flag

The not len(os.listdir(itt_dir)) pattern is unnecessarily verbose. Use the more idiomatic not os.listdir(itt_dir) which directly evaluates the truthiness of the list.
