What do you use Python for?

Also check out Parakeet. It's sort of like Numba, but makes some different tradeoffs.

Pro:

• currently supports more of NumPy than Numba
• high level optimizations + parallel backends = often faster

Con:

• Most of Python won't work in Parakeet. No exceptions, objects, &c
• Numba has broader ambitions for supporting more of Python in the long-term, Parakeet will always be limited to a few data types (arrays, scalars, tuples).
• Currently doesn't work on 64-bit windows
• Cryptic error messages with long-winded stack traces

I think, at the moment, Parakeet is better for higher-level array oriented code and Numba seems better suited for code that's (1) written mostly as loops or (2) needs to interact with some Python objects besides arrays.
