how to create age calculating app using python

Posted by Suraj Singh on February 18, 2017 · 18 mins read
hii readers,

In Today's Tutorial, I am going to teach how you can easily create an age calculating app using python language.

Introduction


Well, In the life of any human being, Age also plays a very important role and Today's Modern world also make it necessary to remember your age. let assume that you working on a computer like any type of Data entry Job and you, again and again, have to calculate the age of client from his/her Date of birth. Yeah, This process is time-consuming and boring.

So, Now let's assume that you created a python script that can calculate age in milliseconds. wow! problem solved.. hahaha...


By The Way, i created this script only for practice purpose so, if you also want to polish your skill then Just take a Try. This Python Script Is Very Easy But Useful. Because Many Times, We Need To Know On Which Day You Born. And What Is Your Correct Age. Or We have to deal with various date and time problems. Therefore this project is going to give you a clear and basic idea actually how you can deal with data and time functions and modules.


How it's Going to Work



Well, Here I am going to create 2 scripts. first one is dob.py which is completely responsible for all date and time function operations and Another Script main.py, which is responsible for Graphical User Interface. In Dob.py, I am going to use DateTime module to play with date and time functions, regular expression module to check user inputs. In main.py, Tkinter for Graphics And Etc Etc.


Because Every Function and codes are clearly visible in Codes. I am going to left Furthur Exercise For readers to Understand it on your own.

Don't worry, For Queries and Suggestion You can use Comment Box.


Example Codes Of Age Calculator


Today, For This Purpose We Will Use Python DateTime module.

Here, I am Sharing My Demo Codes But If You Want More Better Example Then, You Can Modify these codes yourself or Download This Script From My GitHub repository (link given at the end of these codes ).
