The best check for syntax is the Python interpreter. if its happy then
the syntax is fine. You can try pylint and similar tools for more
critical analysis.

Not more efficient no, but for production code you should wrap it
in a try/except block and usually, when reading user input in real
code, we need at least minimal data sanity checks. But you can
wrap that in a function and use the function in the comprehension.
It is a valid use of a comprehension if that's what you are asking.
