How to remove single quotes output?

I have a code, which takes a string from input_file_1 and two numbers to slice the string from input_file_2, the output strings are written in output_file and divided by space:

def task_3(input_file_1, input_file_2, output_file):
    with open(input_file_1) as i_f_1, open(input_file_2) as i_f_2, open(output_file, 'w') as o_f:
        result = []
        for line_1, line_2 in zip(i_f_1.readlines(), i_f_2.readlines()):
            start, finish = line_2.split()
            result.append(line_1[int(start):int(finish)+1])
        o_f.write(' '.join(repr(i) for i in result))

task_3('test_import_file_2_1.txt', 'test_import_file_2_2.txt', 'output_file.txt')

The problem is that output looks like this:

‘tPGRIXNp’ ‘JEflNBYRbuLkOiZqQHYNNTWPUIPNibcIpSL’
‘yDvBXxyOUwjGAemSbsuHupMmGIWpTwv’…

Whereas it must look like this:

tPGRIXNp JEflNBYRbuLkOiZqQHYNNTWPUIPNibcIpSL
yDvBXxyOUwjGAemSbsuHupMmGIWpTwv…

As you can see strings are attached to single quotes, which I can’t get rid off.

>Solution :

You can try removing function "repr"

o_f.write(' '.join(i for i in result))

Also you can provide an example of your input files to reproduce the problem on my computer.
