5.1. Q. Can I create my own functions in C?
@ -1708,6 +1709,22 @@ A. Variables with double leading underscore are "mangled" to provide a
simple but effective way to define class private variables. See the
chapter "New in Release 1.4" in the Python Tutorial.
4.41. Q. How do I delete a file? And other file questions.
A. Use os.remove(filename) or os.unlink(filename); for documentation,
see the posix section of the library manual. They are the same,
unlink() is simply the Unix name for this function. In earlier
versions of Python, only os.unlink() was available.
To remove a directory, use os.rmdir(); use os.mkdir() to create one.
To rename a file, use os.rename().
To truncate a file, open it using f = open(filename, "w+"), and use
f.truncate(offset); offset defaults to the current seek position.
There's also os.ftruncate(fd, offset) for files opened with os.open()
-- for advanced Unix hacks only.
