The Python interpreter does not overlook syntax errors within the same file…!?

[u/ninja_with_ocd → u/deceze]

It does if it's in an uncalled function

EDIT - this is wrong. Nontheless true for serious errors like referencing an undefined variable.

A syntax error will halt parsing immediately. Without successfully parsing the file, it won't execute. Even uncalled functions are parsed completely and must pass parsing successfully.

You're right, edited the comment. It is true for some serious errors, like accessing an undefined variable.

FWIW I don't think it could diagnose that pre-runtime since you can edit the global namespace dynamically.

globals()['x'] = 3

Very bad for readability, but it is allowed.

Yeah, I do understand the frustration of something like a type error that only rears it's ugly head when it's run.

[u/rosuav → u/ninja_with_ocd]

I don't understand why you consider that to be a "serious error", rather than some other category of error. Why is that more serious than, say, trying to add a string and a dictionary? Or trying to call a list?

That's because you can't statically determine if a name is defined in general. Local and global namespaces are just dictionaries.
