The whole point is that you don't need to.

The 't' is non-standard. To open a file for writing in text mode, use "w".
To open a file for writing in binary mode, use "wb".
In text mode, print a single '\n' (no '\r') to mark the end of each
line. This will print the appropriate end-of-line sequence for whatever
system your program is running on.
