To save a NumPy array to a file, we can use the savetext(~) method.
Examples
To save as a text file:
x = np.array([3,4,5])np.savetxt("my_data.txt", x)
This creates the following text file called "my_data" in the same directory as your Python script:
3.000000000000000000e+004.000000000000000000e+005.000000000000000000e+00
