Rank Based Percentile Gui Calculator using Tkinter
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 boxesdef Clear(): # deleting the content from the entry box rankField.delete(0, END) total_participantField.delete(0, END) percentileField.delete(0, END) # Driver Codeif __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() |
