Using python to write text files with DOS line endings on linux

Question

I want to write text files with DOS/Windows line endings \'\\r\\n\' using python running on Linux. It seems to me that there must be a better way than manually putting a \'\\r\\

Answer 1

Just write a file-like that wraps another file-like and which converts \n to \r\n on write.

For example:

class ForcedCrLfFile(file):
    def write(self, s):
        super(ForcedCrLfFile, self).write(s.replace(r'\n', '\r\n'))
