Write a gui-based program that allows the user to convert temperature values between degrees fahrenheit and degrees celsius. the interface should have labeled entry fields for these two values. these components should be arranged in a grid where the labels occupy the first row and the corresponding fields occupy the second row. at start-up, the fahrenheit field should contain 32.0, and the celsius field should contain 0.0. the third row in the window contains two command buttons, labeled > > > > and < < < < . when the user presses the first button, the program should use the data in the celsius field to compute the fahrenheit value, which should then be output to the fahrenheit field. the second button should perform the inverse function.

def CelsiusToFahenheit(Celsius, entry):

  #Celsius = int(input("Enter a temperature in Celsius: "))

  Fahrenheit = 9.0/5.0 * float(Celsius) + 32

  entry. delete(0, 'end')

  entry.insert(0, str(Fahrenheit))

def FahenheitToCelsius(Fahrenheit, entry):

  #!Fahrenheit = int(input("Enter a temperature in Fahrenheit: "))

  Celsius = (float(Fahrenheit) - 32) * 5.0/9.0

  entry. delete(0, 'end')

  entry.insert(0, str(Celsius))

def main():

   window = Tkinter.Tk()

   window.title("Grid")

   lb = Tkinter.Label(window, text='Fahrenheit')

   lb.grid (row=0,column=0)

   lb1=Tkinter.Label(window,text='Celsius:')

   lb1.grid (row=0,column=1)

   en =Tkinter. Entry(window, justify='right')

   en.grid(row=1,column=0)

   en.insert(0, "32.0")

   en1=Tkinter.Entry(window, justify='right')

   en1.grid(row=1,column=1)

   en1.insert(0, "0.0")

   btnFtoc =Tkinter.Button(window, text='>>>>', command=lambda: FahenheitToCelsius(en.get(), en1))

   btnFtoc.grid(row=2,column=0)

   btnCtoF =Tkinter.Button(window, text='<<<<', command=lambda:  CelsiusToFahenheit(en1.get(), en))

   btnCtoF.grid(row=2,column=1)

   window.mainloop()
