Sum of two numbers using Tkinter in python

A simple Sum or addition of two numbers using Tkinter in python. This program will print the addition or sum of the two numbers in the python Tkinter program for python GUI developers and beginners. This framework makes it easy for Python programmers to develop GUI elements using the Tk toolkit’s widgets. Buttons, menus, and data fields can all be made with Tk widgets.

from tkinter import * 
def addNumbers():
res=int(e1.get())+int(e2.get())
myText.set(res)
master = Tk()
myText=StringVar()
Label(master, text="First").grid(row=0, sticky=W)
Label(master, text="Second").grid(row=1, sticky=W)
Label(master, text="Result:").grid(row=3, sticky=W)
result=Label(master, text="", textvariable=myText).grid(row=3,column=1, sticky=W)
e1 = Entry(master)
e2 = Entry(master)
e1.grid(row=0, column=1)
e2.grid(row=1, column=1)
b = Button(master, text="Calculate", command=addNumbers)
b.grid(row=0, column=2,columnspan=2, rowspan=2,sticky=W+E+N+S, padx=5, pady=5)
mainloop()

What is Tkinter program python GUI and name meaning of tkinter

Tkinter is Python’s standard GUI library. When Python is used in conjunction with Tkinter, creating graphical user interfaces is quick and simple. Add the Tkinter module to your project. Create the main window for the GUI program. To the GUI program, add one or more of the above-mentioned widgets.

Tkinter is derived from the Tk interface. Fredrik Lundh is the author of Tkinter. Tkinter is open-source software distributed under the Python license.

Tkinter is a combination of the Tcl and Python standard GUI frameworks that provides all of the widgets you’ll need to create a rich UI for whatever program you’re working on, but it’s especially well-suited for desktop apps.

What is Def function and how it implement in Tkinter python program

The procedure for defining a function in Python is as follows. The keyword def is used to define a function. The name of the function is followed by the parameter(s) in ()

The colon marks the beginning of the function body, which is indented. The return statement determines the value to be returned inside the function body.

The procedure for defining a function in Python is as follows. The keyword def is used to define a function. The return statement determines the value to be returned inside the function body. When a function is called with an argument after it has been defined, it returns a value.

A function is defined by giving it a name, specifying the arguments that must be included in the function, and structuring the code blocks. Once a function’s fundamental structure is complete, you can call it from another function or directly from the Python prompt to run it.

What is Label in python tkinter program

The Label specifies the container box in which text or images can be placed. This widget is used to inform the user about the other widgets that are utilized in the Python application.

The Label specifies the container box in which text or images can be placed. This widget is used to inform the user about the other widgets that are utilised in the Python application. We frequently work with datasets in machine learning that include numerous labels in one or more columns.

Labels in the form of words or numbers can be used. The training data is frequently labelled in words to make it intelligible or human readable.

What is Grid structure in python tkinter program

The widgets are arranged in a two-dimensional table by the Grid geometry manager. Each “cell” in the resulting table can store a widget, and the master widget is divided into a number of rows and columns. Tkinter‘s grid manager is the most adaptable of geometry managers.

The grid() geometry manager arranges widgets in the parent widget in a table-like arrangement. Each part of the table can house a widget, while the master widget is divided into rows and columns. It makes use of the following terms: column, columnspan, ipadx, ipady, padx, pady, row, rowspan, and sticky.
