This part is very intuitive and requires us to add only two lines of code to our __init__ method: The reason we are adding it to the __init__ method is because we want this to be “created” as soon as the application starts. Making these additions to our code, you should arrive at the following: Copy paste the above code into your editor and run it. My calculator does what he asked and I am within the the line limit (Maximum of 300 lines if you were curious. Since our equation line takes up the whole width of the screen, it means that it takes place of exactly 4 columns. Step 6:Specify what should happen when we execute the file.This is quite sequential, so follow the logic.– We first create a local variable root and assign Tk() to it. A graphical user interface is an application that has buttons, windows, and lots of other elements that the user can use to interact with your application. The class Calc() contains all the functions for this piece of code. Notepad & Calculator In Tkinter + Why Tkinter? 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. 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. As the next step what we would like to do is add an equation line to our calculator GUI. I invite you to have a read into the "official" Style Guide for Python Code - section "Documentation Strings" (or this for further reading). For example, if your current_equation is “1+1” and is a string, if you run 1+1 in Python, it will give you 2 as output. Write the code that I provided below into the text editor.
