how to write a numpy array to a file in python
numpy.savetxt(fname, X, fmt='%.18e', delimiter=' ', newline='n',
header='', footer='', comments='# ', encoding=None)
x = y = z = np.arange(0.0,5.0,1.0)
np.savetxt('test.out', x, delimiter=',') # X is an array
np.savetxt('test.out', (x,y,z)) # x,y,z equal sized 1D arrays
np.savetxt('test.out', x, fmt='%1.4e') # use exponential notationsave set of numpy arrays to file py
>>> with open('test.npy', 'wb') as f:
np.save(f, np.array([1, 2]))
np.save(f, np.array([1, 3]))
>>> with open('test.npy', 'rb') as f:
a = np.load(f)
b = np.load(f)
>>> print(a, b)
