The code will make a GUI window in Python that would ask a user to input the length. The user will get values in different units when asked to convert.
In this tutorial, we will be making a GUI window using Tkinter GUI in python. We will go through the basic libraries and concepts and codes in Tkinter.
What this code does is, it will make a GUI window that would ask a user to input length in meters, when done and asked to convert would display values of lengths in different units.
GUI stands for Graphical User Interface, which helps us the users to interact with the machine in a more fun way or through an interface. Tkinter is the method that provides a toolkit for GUI.
As we are starting with the code some steps are to be remembered.
Importing the module
from tkinter import*
Includes all the names of Tkinter to the code
Initializing the variable
window=Tk()
To create the main window, Tkinter offers a method TK().
Creation of window
You can add title and window geometry to add details to your window.
Adding widgets to it
In this code the widgets used are
Button: this is used to place buttons in Tkinter
Label: A single line widget that displays a box where text can be inserted
Entry: This is the input widget, any single line input is accepted here.
Text: Inserts text in Tkinter
Closing through a variable in mainloop()
This is the final closing statement in your code. It tells python to run the code in loops until the window is closed.
Getting started with the code
After creating a window, using below code
from tkinter import * # Create a GUI window window = Tk() window.title("Lenght Converter") window.geometry("500x300+550+355")
We need to place widgets for which we would use the label as
e10 = Label(window, text = 'dm',bg="light gray")
here, we can insert text to our label added with color
Also, text widget is used as
t8 = Text(window, height = 1, width = 15)
Here, height and width can be added to your text
The button widget is used as
exit_button = Button(window, text="Exit", command=window.destroy) exit_button.place(x=450,y=255)
Here, the button widget is used as an exit to the window. When the button is clicked, the application terminates.
Defining of length converter function
Initializing variables and converting them to their values is done in function.
def lengthconv(): km = float(e2_value.get())*1000 mm = float(e2_value.get())/1000 cm = float(e2_value.get())/100 mile=float(e2_value.get())*0.00062 yard=float(e2_value.get())*1.094 inch=float(e2_value.get())*39.37 foot=float(e2_value.get())*3.281 dm=float(e2_value.get())*10
Complete code:
from tkinter import * # Create a GUI window window = Tk() window.title("Lenght Converter") window.geometry("500x300+550+355") def lengthconv(): km = float(e2_value.get())*1000 mm = float(e2_value.get())/1000 cm = float(e2_value.get())/100 mile=float(e2_value.get())*0.00062 yard=float(e2_value.get())*1.094 inch=float(e2_value.get())*39.37 foot=float(e2_value.get())*3.281 dm=float(e2_value.get())*10 t1.delete("1.0", END) t1.insert(END,km) t2.delete("1.0", END) t2.insert(END,mm) t3.delete("1.0", END) t3.insert(END,cm) t4.delete("1.0", END) t4.insert(END,mile) t5.delete("1.0", END) t5.insert(END,yard) t6.delete("1.0", END) t6.insert(END,inch) t7.delete("1.0", END) t7.insert(END,foot) t8.delete("1.0", END) t8.insert(END,dm) # Creating Label widgets e1 = Label(window, text = "Enter length in meters",bg="light gray") e2_value = StringVar() e2 = Entry(window, textvariable = e2_value) e3 = Label(window, text = 'km',bg="light gray") e4 = Label(window, text = 'mm',bg="light gray") e5 = Label(window, text = 'cm',bg="light gray") e6 = Label(window, text = 'mile',bg="light gray") e7 = Label(window, text = 'yard',bg="light gray") e8 = Label(window, text = 'inch',bg="light gray") e9 = Label(window, text = 'foot',bg="light gray") e10 = Label(window, text = 'dm',bg="light gray") # Creating Text Widgets t1 = Text(window, height = 1, width = 15) t2 = Text(window, height = 1, width = 15) t3 = Text(window, height = 1, width = 15) t4 = Text(window, height = 1, width = 15) t5 = Text(window, height = 1, width = 15) t6 = Text(window, height = 1, width = 15) t7 = Text(window, height = 1, width = 15) t8 = Text(window, height = 1, width = 15) # Creating Button Widget b1 = Button(window, text = "Convert", command = lengthconv) e1.grid(row = 0, column = 0,padx=10,pady=10) e2.grid(row = 0, column = 1,pady=10,padx=10) e3.grid(row = 4, column = 0,pady=10,padx=10) e4.grid(row = 2, column = 0,pady=10,padx=10) e5.grid(row = 3, column = 0,pady=10,padx=10) e6.grid(row = 2, column = 2,pady=10,padx=10) e7.grid(row = 4, column = 2,pady=10,padx=10) e8.grid(row = 3, column = 2,pady=10,padx=10) e9.grid(row = 5, column = 0,pady=10,padx=10) e10.grid(row = 5, column = 2,pady=10,padx=10) t1.grid(row = 4, column = 1,pady=10,padx=10) t2.grid(row = 2, column = 1,pady=10,padx=10) t3.grid(row = 3, column = 1,pady=10,padx=10) t4.grid(row = 2, column = 3,pady=10,padx=10) t5.grid(row = 4, column = 3,pady=10,padx=10) t6.grid(row = 3, column = 3,pady=10,padx=10) t7.grid(row = 5, column = 1,pady=10,padx=10) t8.grid(row = 5, column = 3,pady=10,padx=10) b1.grid(row = 1, column = 1,padx=10,pady=10) exit_button = Button(window, text="Exit", command=window.destroy) exit_button.place(x=450,y=255) window.mainloop()
