Parameters --- fname : filename or file handle If the filename ends in ``.gz``, the file is automatically saved in compressed gzip format. `loadtxt` understands gzipped files transparently. X : 1D or 2D array_like Data to be saved to a text file. fmt : str or sequence of strs,...
NumPy provides functions to read from and write to text files. The primary functions for these operations are numpy.loadtxt() and numpy.savetxt().The numpy.loadtxt() FunctionThe numpy.loadtxt() function loads data from a text file into a NumPy array. It can handle different data types ...
