[SciPy-User] Saving into file.txt

[Oleksandr Huziy]

Transposing the array does the trick:

In [1]: import numpy as np

In [2]: x = np.arange(10)

In [3]: y = np.random.randn(10)

In [4]: y
Out[4]:
array([ 0.77039544,  1.27781447,  0.96214621, -0.04514849,  0.12023634,
        0.33786337, -0.88450054, -0.67355859,  2.11181118,  0.96484793])

In [5]: x
Out[5]: array([0, 1, 2, 3, 4, 5, 6, 7, 8, 9])

In [9]: np.savetxt("test.txt", [x, y])

In [10]: cat test.txt
