374 views

To check if a Python script is valid, use a linter or parser. For a quick syntax check, run the script with the `-m py_compile` option, e.g., `python -m py_compile script.py`. This command compiles the script without executing it, highlighting syntax errors. Linters like `pylint` or `flake8` can also be used for a thorough analysis, providing insights on both syntax and style issues.
