Question

Add radio button options for filing status to the tax calculator program of Project 1. The user selects one of these options to determine the tax rate. The Single option’s rate is 20%. The Married option is 15%. The Divorced option is 10%. The default option is Single.

For the calculations from Project 1, I was gonna use this.

TAX_RATE = 0.20

STANDARD_DEDUCTION = 10000.0

DEPENDENT_DEDUCTION = 3000.0

# Request the inputs gross

Income = float(input("Enter the gross income: "))

numDepend = int(input("Enter the number of dependents: "))

# sets the value for TAX_RATE

option = int(input("Select 1 of these : 1.Single 2.Married 3.Divorced "))

if option == 2 :

TAX_RATE = 0.15

elif option == 3 :

TAX_RATE = 0.10

# Compute the income tax

taxableIncome = grossIncome - STANDARD_DEDUCTION - \

DEPENDENT_DEDUCTION * numDepend

incomeTax = taxableIncome * TAX_RATE

# Display the income tax

print("The income tax is $" + str(incomeTax))

And what I have for implementing this in a GUI is as follows:

from breezypythongui import EasyFrame

class TaxCalculator(EasyFrame):

    """Application window for the tax calculator."""

    def __init__(self):

        """Sets up the window and the widgets."""

        EasyFrame.__init__(self, title = "Tax Calculator")

        # Label and field for the income

        # (self.incomeField)

        # Label and field for the number of dependents

        # (self.depField)

        # Radio buttons for filing status

        # Button group (self.statusGroup)

        # Option for single (self.single)

        # Option for married (self.married)

        # Option for divorced (self.divorced)

        # The compute button

        # Label and field for the tax

        # (self.taxField)

    # The event handler method for the button

    def computeTax(self):

        """Obtains the data from the input field and uses

        them to compute the tax, which is sent to the

        output field (taxField)."""

        pass

        

        

def main():

    TaxCalculator().mainloop()

if __name__ == "__main__":

    main()

Thanks

As project 1 is not known ..use the below radio button code in your project of python.

___________________________

# import tkinter for python gui elements

from tkinter import *

# function definition

def tax():

# assuming some amount to find the tax amount

amount = 35000

# if the selected option is 'single' then get 20% of assumed amount

if var.get() == 1:

tax_amt = 0.2 * amount

# if 'married' then 15% of assumed amount

elif var.get() == 2:

tax_amt = 0.15 * amount

# if divorced then 10% of assumed amount

elif var.get() == 3:

tax_amt = 0.1 * amount

# some display text

disp = "Taxable amount based on the selection is : " + str(tax_amt)

# set the label (which is created in the following steps) with the display text

label.config(text = disp)

# prepare a root window

root = Tk()

# name the root window

root.title("Tax calculator")

# mention the dimension of root window

root.geometry("300x200")

# initialize the variable as integer

var = IntVar()

# set the integer value to 1 i.e, first radio button selection by default

var.set(1)  

# create buttons and place them in window as required

R1 = Radiobutton(root, text = "Single", variable = var, value = 1)

R1.place(x=50,y=50)

R2 = Radiobutton(root, text = "Married", variable = var, value = 2)

R2.place(x=50,y=80)

R3 = Radiobutton(root, text = "Divorced", variable = var, value = 3)

R3.place(x=50,y=110)

# create button and call the function when this button clicked

calculate_button = Button(root, text="Calculate", command=tax)

calculate_button.place(x=50, y=140)

  

# create another button to close the window

quit_button = Button(root, text="Quit", command=root.quit)

quit_button.place(x=130, y=140)

# create a label and place it so that the display text in window is displayed as expected

label = Label(root)

label.place(x=20, y=20)

# call mainloop() to start the event

root.mainloop()
