Digital Employee Registrar, python script can be used to record employee information and retrieve that information by providing reference input like Day, Working Hour and so on.

This script creates a binary file called ‘data.bin’ on your script directory for maintaining a record and it is used while recording and retrieving data during execution of the script. This script is tested under python 2.7 and worked fine. To make it work on your system change shebang line and provide an appropriate interpreter location and make sure you have python version 2.7x installed in your system otherwise simply precede ‘script name’ with ‘python’ and make sure you provide execute permission for this script.

Module Used:

1. Pickle
2. Os
