The NumPy module
The fields of Scientific Research, Medical Imaging, Social Networking, Financial Data Analysis and other areas where intense data processing is involved all have one thing in common. Reading, computing and writing using multi-dimensional data of large...and very large sizes.
The Python module NumPy offers interfaces for creating multi-dimensional arrays, to perform statistical, logical and mathematical operations on them and for reading them from disk to physical memory of the computer system and for writing the processed results back into disk.
