Is NumPy faster than Python?

3 Answers. numpy.abs() is slower than abs() because it also handles Numpy arrays: it contains additional code that provides this flexibility. (PS: ‘[abs(x) for x in a]’ is slower in Python 2.7 than the better map(abs, a) , which is about 30 % faster—which is still much slower than NumPy.)

Why do we use NumPy?

1. NumPy uses much less memory to store data. The NumPy arrays takes significantly less amount of memory as compared to python lists. It also provides a mechanism of specifying the data types of the contents, which allows further optimisation of the code.
