Python method ttyname() returns a string, which specifies the terminal device associated with fd. If fd is not associated with a terminal device, an exception is raised.
Following is the syntax for ttyname() method −
fd − This is the file descriptor.
This method returns a string which specifies the terminal device.
The following example shows the usage of ttyname() method.
# !/usr/bin/python import os, sys # Showing current directory print "Current working dir :%s" %os.getcwd() # Changing dir to /dev/tty fd = os.open("/dev/tty",os.O_RDONLY) p = os.ttyname(fd) print "the terminal device associated is: " print p print "done!!" os.close(fd) print "Closed the file successfully!!"
When we run above program, it produces following result −
Current working dir is :/tmp the terminal device associated is: /dev/tty done!! Closed the file successfully!!
