How to write the output of a python in a text file in separated lines?

Question

I want to write the output of my phyton program in a text file. The output is in a loop and I want that each output be in one line. I am using this code for writing, but still I will give all the result in one line.

with open('temp.txt', 'w') as outfile:
    out = P2[16:3276,:].sum(axis=0)
    outfile.write("{}\n".format(out))

The actual result is:

[ 0.  0.  0. ...,  0.  0.  0.]

But I want to be like this:

Use str.join instead:

with open('temp.txt', 'w') as outfile:
    out = P2[16:3276,:].sum(axis=0)
    outfile.write("\n".join(map(lambda x: '%f' % x, out)))

Thanks. But my output is mot string. With this code I will have this error: sequence item 0: expected str instance, numpy.float32 found – Zahra Jul 19 '19 at 06:37
I did not down vote your answer. It will be a -1 for me, so I did not. – Jul 19 '19 at 06:38
@Zahra Try now. – U13-Forward Jul 19 '19 at 06:39
Thank you. It is working now. But for some of out put I will have scientific numbers like "3.23108e-08". Do you how can I avoid to have this and just have some float numbers? – Zahra Jul 19 '19 at 06:43

u can use replace, depend what's your output, but it can work

r = { "[": "", ".": "\n", "]": ""}

for x,y in r.items():
        out = out.replace(x, y)
