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()
, while having a "n"
between each user input variable(the object of write()
).
I came up with:
nl = "n" lines = line1, nl, line2, nl, line3, nl textdoc.writelines(lines)
If I try to do:
textdoc.write(lines)
I get an error. But if I type:
textdoc.write(line1 + "n" + line2 + ....)
Then it works fine. Why am I unable to use a string for a newline in write()
but I can use it in writelines()
?

Answer
writelines
expects an iterable of stringswrite
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)
.
