Python - write() versus writelines() and concatenated strings

Question

So I\'m learning Python. I am going through the lessons and ran into a problem where I had to condense a great many target.write() into a single write()

Answer 1

• writelines expects an iterable of strings
• write expects a single string.

line1 + "\n" + line2 merges those strings together into a single string before passing it to write.

Note that if you have many lines, you may want to use "\n".join(list_of_lines).
