How to set vertical the ouput in python?

Question

I would like to create an output in `.txt format in python. The problem is that the results are showing horizontally.

How can I set my values vertically?

for example my output has the format:

[6.48421466 4.28001787 6.76134729 5.45509747 7.68957008 3.25036695
 5.26088052 4.45128821 3.99247354 4.04626299 3.19329872 5.21477152
 5.75235725 5.4032342  4.75781543 4.86203242 4.94567754 6.2735008
 3.90191443 3.34211125 4.80198239 5.39782033 4.65575587 4.09630464
 4.68439523 4.24076152 2.70145788 3.18283344 2.67654271 6.71627663

 4.22884378 3.75609531 4.54537646 4.82880385 4.4317394  4.69930332
 5.46046878 3.38346653 4.02209524 4.73886735 4.91038119 3.83070474
 3.46198489 4.89056201 3.45052842 3.60843658 5.38378215 5.82383583

 5.51898447 4.75482025 4.43989681 4.71631944 5.04887236 4.16837725]

I have tried:

with open('outputdata.txt','w',encoding='utf-8') as fout:
     fout.writelines(str(A))

and

with open('outputdata.txt','w',encoding='utf-8') as fout:
     fout.write(str(A)+'\n')

But it is no use. My results are showing horizontally, and not vertically (with a column format I mean)

Answer 1

I assume this is your data:

a = [6.48421466, 4.28001787, 6.76134729, 5.45509747, 7.68957008, 3.25036695, 5.26088052, 4.45128821, 3.99247354, 4.04626299, 3.19329872, 5.21477152, 5.75235725, 5.4032342, 4.75781543, 4.86203242, 4.94567754, 6.2735008, 3.90191443, 3.34211125, 4.80198239, 5.39782033, 4.65575587, 4.09630464, 4.68439523, 4.24076152, 2.70145788, 3.18283344, 2.67654271, 6.71627663, 3.99750959, 4.55231039, 6.57358438, 4.59699555, 3.37902555, 4.60574622, 5.7602282, 5.34084772, 4.2033163, 4.41813674, 5.83988272, 4.56814295, 4.22884378, 3.75609531, 4.54537646, 4.82880385, 4.4317394, 4.69930332, 5.46046878, 3.38346653, 4.02209524, 4.73886735, 4.91038119, 3.83070474, 3.46198489, 4.89056201, 3.45052842, 3.60843658, 5.38378215, 5.82383583, 3.37329096, 3.72459568, 5.42039616, 5.4329635, 5.16597499, 3.61643261, 5.51898447, 4.75482025, 4.43989681, 4.71631944, 5.04887236, 4.16837725]

You can use:

with open('outputdata.txt', 'w',) as f:
    f.writelines([str(x) + '\n' for x in a])

which results in

6.48421466
4.28001787
6.76134729
5.45509747
7.68957008
3.25036695
5.26088052
4.45128821
3.99247354
