Creating Your First Application On Python Using Tkinter

What is Tkinter

For those who don't know what tkinter is, It is basically a python module for making GUI(Graphical User Interface), in which we can do all the beautiful things on the frontend and hide your messy backend code😅..

Getting Started

First off to get started, we need to Install Tkinter using pip
On your terminal type,

pip install tk

Note: You will need the latest version of python(3.9.0) or higher.

Now to the fun stuff 👾👾..

After installing tkinter, you are ready to make your first python application.
On your text-editor, create a python file(.py) and then you'll be needing the following code to set up tkinter on your application.

#importing the tkinter module
from tkinter import *
import tkinter

#assigning a "root" as the main window for our application
root = tkinter.Tk()

root.mainloop()

Now if you run the following code, you can see a window as shown below.

This is the place all of our widgets which are the elements are going to be shown.

Before we go ahead, We need to make a fixed size for our application.
Just after assigning the root = tkinter.Tk() add,

root.geometry('500x500')

What is better than making a "Hello World!" program?

Now we're going to a widget by tkinter which lets us make some cool text.

#Just a basic text.
Label(root, text="Hello World!").pack()

#Just a basic text but bigger.
Label(root, text="Hello World!", font=20).pack()

#A bold text with a different font
Label(root, text="Hello World!", font=('Jokerman',25,'bold')).pack()

#A text with red background
Label(root, text="Hello World!",bg='red', font=10 ).pack()

#A text with red color
Label(root, text="Hello World!",fg='red', font=10 ).pack()

Here's the complete code of the program that we just made,

#importing the tkinter module
from tkinter import *
import tkinter

root = tkinter.Tk()
root.geometry('500x500')
#Main
#Just a basic text.
Label(root, text="Hello World!").pack()
#Just a basic text but bigger.
Label(root, text="Hello World!", font=20).pack()
#A bold text with a different font
Label(root, text="Hello World!", font=('Jokerman',25,'bold')).pack()
#A text with red background
Label(root, text="Hello World!",bg='red', font=10 ).pack()
#A text with red color
Label(root, text="Hello World!",fg='red', font=10 ).pack()
root.mainloop()
