如何在Python中从文本文件导入矩阵

Question

Hey this might be a simple question, but I have never had to import any files into Python before.

So I have a numpy Matrix in a text file, named dmatrix.txt , so how would I be able to import the file into Python and use the matrix?

I am trying to use numpy.load() , but I am unsure how to use it.

Try numpy.loadtxt('dmatrix.txt') ; you could add a delimiter argument if the file is comma-separated or something.

numpy.load is for files in numpy/python binary formats - created by numpy.save , numpy.savez , or pickle .
