Step 1:Create a Calculator class (which is an individual object with specified behaviour). Here is a Calculator_GUI() class. Step 3:Here we start adding logic for the clicks, and the simplest one to do is what should be the action performed by the calculator in Python when a user clicks “c”? This is a standard procedure and you can read find more details here. < Essentially this step created a GUI by telling a class to use root which is Tk() as it’s main window.– Lastly we add root.mainloop() where mainloop() is a method of Tk() basically telling the app to wait for events (clicks) and update the UI accordingly.

You can boost the beauty of your Tkinter apps with these few lines of First Python GUI Calculator with exponentiation function and percents. Step 1:We need to create some equation line that we want to add to our Calculator class, hence we define it as self.equation and then use a tkinter class Entry() to create a widget.There are a few arguments that go into the Entry() class. Step 3:Arrange buttons into rows in which they appear on the calculator. There are three main parts of this GUI Calculator . This will be our main frame on top of which we will be adding the GUI and calculator functionality. We don’t need to use any file named as file.kv for building a calculator, as a calculator is a very simple application. Since our equation line takes up the whole width of the screen, it means that it takes place of exactly 4 columns. Since Tkinter is cross-platform so it works on both windows and Linux.If you are a beginner, and want to learn some basic GUI with python, this will be helpful for you. We would want the equation line cleared if a user clicks “c”, and this is exactly what we do by using .delete() method of the equation line which is a tkinter Entry class. So, I'll explain the code you've given as best I understand it. The project is currently focussing on the PythonCard GUI system on the Python side 2 Reviews. I will place at the top of our GUI . Tkinter provides a powerful object-oriented interface to the Tk GUI toolkit. Step 2:We create a Button class with a few parameters that we need:–self.master: this assigns the Button object to the Calculator class.–text=value: this will display the “value” we passed as an argument as text on the button.–width=9: this is just styling, and you can adjust the width of the buttons. The key widget in our GUI was the button. The reason for the error is that we used some addButton() method inside our createButton() method, but we haven’t specified what exactly it does. To do that we need to go back to our addButton() method and add one more parameter to the Button() object creation.
