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

For Python 2.6 and later, the open function in the io module has an optional newline parameter that lets you specify which newlines you want to use.

For example:

import io
with io.open('tmpfile', 'w', newline='\r\n') as f:
    f.write(u'foo\nbar\nbaz\n')

will create a file that contains this:

foo\r\n
bar\r\n
baz\r\n
