Python: Writing a numpy array to txt file

Question

I have some data in an array with 5 columns and a lot of rows.

I want to save this in a txt file by doing:

for i in range(rows):
    with open ('datos_practica.txt','a') as f:
        line=str(data[i,:])
        f.write(line)
        f.write('\n')

But instead of getting printing 5 columns in the txt file:

00 01 02 03 04

and so on........

It writes the last column below the first one

00 01 02 03

04

and so on....

Any clues for this issue? Thanks in advance.

Answer 1

Use this code instead:

np.savetxt("array.txt", np.array(your array))
