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\n' at the end of every line or using a line ending conversion utility. Ideally I would like to be able to do something like assign to os.linesep the separator that I want to use when writing the file. Or specify the line separator when I open the file.

Answer 1

you can look at this PEP for some reference.

Update:

@OP, you can try creating something like this

import sys
plat={"win32":"\r\n", 'linux':"\n" } # add macos as well
platform=sys.platform
...
o.write( line + plat[platform] )

Answer 2

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

Answer 3

I found a good answer 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.

Answer 4

You could write a function that converts text then writes it. For example:

def DOSwrite(f, text):
    t2 = text.replace('\n', '\r\n')
    f.write(t2)
#example
f = open('/path/to/file')
DOSwrite(f, "line 1\nline 2")
f.close()
