5. Extending Python

Python is fast enough for the vast majority of programs. And in those cases where it isn’t, we can often achieve sufficient speedups by using concurrency, as we saw in the previous chapter. Sometimes, though, we really do need to do faster processing. There are three key ways we can make our Python programs run faster: we can use PyPy (pypy.org), which has a built-in JIT (Just in Time compiler); we can use C or C++ code for time-critical processing; or we can compile our Python (or Cython) code into C using Cython.*
