How to set vertical the ouput in python?

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

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

Writing to a file will always be horizontally unless you manually write each value in a different line. I suggest you use this simple foreach loop:

with open('outputdata.txt','w') as fout:
    foreach item in A:
        fout.write(str(item) + "n")

Of course, you can add “[” at the beginning and “]” at the end if necessary. Good Luck!
