It's documented. Not necessarily very well, but it's documented.
Type help(file.close) at the interactive prompt.
close(...)
close() -> None or (perhaps) an integer. Close the file.
Sets data attribute .closed to True. A closed file cannot be used
for
further I/O operations. close() may be called more than once
without
error. Some kinds of file objects (for example, opened by
popen())
may return an exit status upon closing.

def quiet_close(fp):
"""Close a file, silently ignoring errors."""
try:
fp.close()
except IOError:
pass
