[Numpy-discussion] how to save a large array into a file quickly

[frank wang]

Hi,
 
I have a large ndarray that I want to dump to a file. I know that I can use a for loop to write one data at a time. Since Python is a very powerfully language, I want to find a way that will dump the data fast and clean. The data can be in floating point or integer.
 
Thanks
 
Frank
