How to use "\n" while writing to files [duplicate]

            for k,v in list1:
                outputFile.write(k + "\n")

The list1 is of type (char,int) The problem here is that when I execute this, file doesn't get separated by "\n" as expected. Any idea what is the problem here ? I think it is because of the

Any help is appreciated. Thanks in advance. (I am using Python 3.4 with "Python Tools for Visual Studio" version 2.2)

Answer 1

If you are on windows the \n doesn't terminate a line.
Honestly, I'm surprised you are having a problem, by default any file opened in text mode would automatically convert the \n to os.linesep. I have no idea what codecs.open() is but it must be opening the file in binary mode.
Given that is the case you need to explicitly add os.linesep:

outputFile.write(k + os.linesep)

Obviously you have to import os somewhere.

How would I specify a new line in Python?

I had to use "\r\n" as in Windows, "\r\n" will work.
