A good solution has been posted bye @micseydel.
Working code both do the same:

lst = ['line 1', 'line 2', 'line 3']

# Yes
with open('out_1.txt', 'w') as f_out:
    f_out.write('\n'.join(lst))

# No
with open('out_2.txt', 'w') as target:
    target.write(lst[0]);target.write("\n");target.write(lst[1]);target.write("\n");target.write(lst[2]);target.write("\n")
