os.closerange() - os

             
The method closerange() closes all file descriptors from fd_low (inclusive) to fd_high (exclusive), ignoring errors.This method is introduced in Python version 2.6.


fd_low -- This is the Lowest file descriptor to be closed.
fd_high -- This is the Highest file descriptor to be closed.

Syntax

os.closerange(fd_low, fd_high);

Example

for fd in xrange(fd_low, fd_high):
    try:
        os.close(fd)
    except OSError:
        pass

Output / Return Value

This would create given file foo.txt and then write given content in that file.This will produce the following result:


#!/usr/bin/python

import os, sys

# Open a file
fd = os.open( "foo.txt", os.O_RDWR|os.O_CREAT )

# Write one string
os.write(fd, "This is test")

# Close a single opened file
os.closerange( fd, fd)

print "Closed all the files successfully!!"
