class PI:
pi = 0

def calculate_pi(self,n):
    sum = 0
    for j in range(0,n):
      sum += (math.pow(-1,j)/((2*j)+1))
      pi = 4 * sum
    return float(pi)

def use_pi(self,r,pi):
    radius = r
    area = pi * radius * radius
    return float(area)

tkMessageBox.showinfo( "Result", result )

# Window
top_window = Tk()

# Input 1
l1 = Label(
top_window, text="Number of values to use in PI Calculation " )
i1 = Entry(top_window, bd=5)
l1.grid(row=0, column=0, padx=10, pady=10)
i1.grid(row=0, column=1, padx=10, pady=10)

# Input 2
l2 = Label(
top_window, text="Radius of the circle " )
i2 = Entry(top_window, bd=5)
l2.grid(row=1, column=0, padx=10, pady=10)

b1 = Button(
