Welcome folks today in this post we will be building a birthday age calculator gui desktop app using pyqt5 in python. All the full source code of the application is given below.
Get Started
In order to get started you need to install the following library using the pip command as shown below
pip install pyqt5
After installing this library we need to make an app.py file and copy paste the following code
