A generalised try_convert method would be useful, but I think I would rather see a one-line version of the try statements, perhaps something like this:
x = try float('some text') else 42 if ValueError
for parallelism with if/else operator I'd like
float('some text') except ValueError then 42
which is equivalent to calling:
def f(): try: return float('some text') except ValueError return 42
For example,
float(foo) except ValueError then None if foo else 0
or equivalently:
float(foo) if foo else 0 except ValueError then None
Of course this requires a new keyword so the chances of this being added are slim.
