how to show a value to the user? - elhetch - Feb-11-2017
i created the below code to do some math, i would like to know how to show the value after running the code to the user?
import math
from Tkinter import *
def circle_weight():
area = math.pi*int(ent1.get())**2
weight = area*int(ent2.get())
print weight
master = Tk()
master.title("Disc Weight Calculator")
master.geometry("300x300")
master.wm_iconbitmap('steel-alloy.ico')
lbl1=Label(master,text="Radius",bg="cornsilk")
ent1=Entry(master)
lbl1.pack()
ent1.pack()
lbl2=Label(master,text="Thk")
ent2=Entry(master)
lbl2.pack()
ent2.pack()
btn=Button(master,text="Calculate",command=circle_weight)
btn.pack()
master.mainloop()

create a label and use the textvariable to make it change on the fly of the button

The code will be of similar shape to what you have already but will be a little longer vertically.

The link i showed you has a tutorial for label and the argument textvariable.
import math
from Tkinter import *
def circle_weight():
area = math.pi*int(ent1.get())**2
weight = area*int(ent2.get())
print weight
v.set(weight)
master = Tk()
master.title("Disc Weight Calculator")
master.geometry("300x300")
#master.wm_iconbitmap('steel-alloy.ico')
v=IntVar()
output = Label(master, textvariable=v)
lbl1=Label(master,text="Radius",bg="cornsilk")
ent1=Entry(master)
lbl1.pack()
ent1.pack()
lbl2=Label(master,text="Thk")
ent2=Entry(master)
lbl2.pack()
ent2.pack()
btn=Button(master,text="Calculate",command=circle_weight)
btn.pack()
output.pack()
master.mainloop()@Yoriz
