I suspect most of the poll respondents see NumPy as representing a lot more than just a fast ndarray-- i.e. that being able to type import numpy is the key to being able to tap the whole scientific Python ecosystem. I cannot be certain, but the I am willing to bet the percentage of people who use NumPy and NumPy only relative to the rest of the scientific Python community is very small. > So, I NEED SciPy, and would like to also have PyPy, and I'd like to use them > together rather than having to separate everything into separate scripts, > some of which use CPython/SciPy and some of which use PyPy.
