On Just One line - Fumi - Jan-25-2018
Hi there,
Does anyone know how to condense the following into one line as target.write()
target.write (line1)
target.write ("\n")
target.write (line2)
target.write ("\n")
target.write (line3)
target.write ("\n")Kind Regards

Perhaps something like this:
lines = (line1, line2, line3)
target.write("{lines[0]}{newline}{lines[1]}{newline}{lines[2]}{newline}".format(lines=lines, newline="\n"))Though I am certain there are more elegant and optimal solutions :)

A few attempts (not tested)...
Potentially large memory usage
target.write('\n'.join([line1, line2, line3]))One line, after importfrom itertools import chain, repeat
target.writelines(chain(*zip([line1, line2, line3], repeat('\n'))))

Well I found a simple way eventually.
target.write(line1);target.write("\n");target.write(line2);target.write("\n");target.write(line3);target.write("\n")

Calling write 6 times
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")
