+# Website Blocker using Python
+This is a program which blocks certain distracting website like Facebook, Youtube etc during your work hours.
+
+## Libraby Used
+time (datetime is imported from python)
+
+## Host Files
+Host is an operating system file which maps hostnames to IP addresses.
+Using python file handling manipulation I have changed hostnames on the hosts files for a certain interval of day when I'm working and need no distraction and deleted it then after when the time is over.
+
+## Location of host file
+### Host file on Mac and Linux :
+    $ /etc/hosts
+
+### Host file on windows :
+    $ C:\Windows\System32\drivers\etc
+
+## Note
+* Windows user need to create a duplicate of OS’s host file. Now provide the path of the duplicate file in hosts_path mentioned in the script.
+* For scheduling above script in Linux you have to open crontab in your terminal as a root.(use sudo command)
