That's a relative term. Go will give you static type safety (until and unless you [inevitably ;)] break out into the 'reflect' package) and strong assumptions about what default values mean in data structures. These are very nice features to have in terms of trading off flexibility for expressiveness.

Python is not a language I would trust in healthcare, finance, etc. on the critical path of consuming and transforming user-supplied data. Go I'd be comfortable with.
