Prerequisites:
Python offers multiple options for developing a GUI (Graphical User Interface). Out of all the GUI methods, Tkinter is the most commonly used method. In this article, we will learn how to create a Rank Based – Percentile Gui Calculator application using Tkinter, with a step-by-step guide.
To create a Tkinter:
- Importing the module – Tkinter
- Create the main window (container)
- Add any number of widgets to the main window.
- Apply the event Trigger on the widgets.
The GUI would look like below:
Let’s create a GUI based simple Rank Based – Percentile Gui Calculator application :
Below is the implementation :
Python3
# import all functions from the tkinter from tkinter import * # Function to calculate the percentile def getPercentile() : # take a value from the respective entry boxes # get method returns current text as string students = int (total_participantField.get()) rank = int (rankField.get()) # variable to store the result upto 3 # decimal points result = round ((students - rank) / students * 100 , 3 ); # insert method inserting the # value in the text entry box. percentileField.insert( 10 , str (result)) # Function for clearing the # contents of all text entry boxes def Clear(): # deleting the content from the entry box rankField.delete( 0 , END) total_participantField.delete( 0 , END) percentileField.delete( 0 , END) # Driver Code if __name__ = = "__main__" : # Create a GUI window gui = Tk() # Set the background colour of GUI window gui.configure(background = "light green" ) # set the name of tkinter GUI window gui.title( "Rank Based- Percentile Calculator" ) # Set the configuration of GUI window gui.geometry( "650x200" ) # Create a Rank: label rank = Label(gui, text = "Rank" , bg = "blue" ) # Create a And: label andl = Label(gui, text = "And" , bg = "blue" ) # Create a Total Participants : label total_participant = Label(gui, text = "Total Participants" , bg = "blue" ) # Create a Find Percentile Button and # attached to getPercentile function find = Button(gui, text = "Find Percentile" , fg = "Black" , bg = "Red" , command = getPercentile) # Create a Percentile : label percentile = Label(gui, text = "Percentile" , bg = "blue" ) # Create a Clear Button and attached # to Clear function clear = Button(gui, text = "Clear" , fg = "Black" , bg = "Red" , command = Clear) # grid method is used for placing # the widgets at respective positions # in table like structure . # padx attributed provide x-axis margin # from the root window to the widget. rank.grid(row = 1 , column = 1 ,padx = 10 ) andl.grid(row = 1 , column = 4 ) total_participant.grid(row = 1 , column = 6 , padx = 10 ) # pady attributed provide y-axis # margin from the widget. find.grid(row = 3 , column = 4 ,pady = 10 ) percentile.grid(row = 4 , column = 3 ,padx = 10 ) clear.grid(row = 5 , column = 4 ,pady = 10 ) # Create a text entry box for filling or # typing the information. rankField = Entry(gui) total_participantField = Entry(gui) percentileField = Entry(gui) # grid method is used for placing # the widgets at respective positions # in table like structure . rankField.grid(row = 1 , column = 2 ) total_participantField.grid(row = 1 , column = 7 ) percentileField.grid(row = 4 , column = 4 ) # Start the GUI gui.mainloop() |
