By learning the basic concepts on python you can create/build a Calculator by adding some extra files and features. In this project, I have created a simple Calculator with simple and basic function of Python.Once you understand a single line and its function , it won't be hard enough to understand the whole function for this project.
This is how my Calculator looks like.
Well it is still not looking that perfect because of the position is still not fixed properly. Moreover, I am using tkinter file to create the calculator and some of the features of this files are not working on Mac. So I finally ended up with this look.
