Not quite the same. Yes- superBasic runs uncompiled but errors only show when
they are encountered.
Python (and perl - my preference) compiles first, syntax errors show then and
it stops with error display - often wildly confusing if things lke closing
quotes (or a dreaded ';' in Perl) is missed. Only if it compiles does it run
the program.

One of the really great features of python is no {} structure or semi-colons -
it relies on indenting. This imposes good layout, which I in fact always
attempt in perl ( and C).
I always thought it was a pity superBasic demanded line numbers. They were not
actually necessary, and if GOTO did not exist, not even used.
