    Using ".get()" with "entry"(TKinter)?

    Hello, I´m new to Python.. so this is a newbee question.

    I´d like to put the value enterd in the entryfield in a variable.

    I´m trying to build a calculator with python and TKinter, coding it in just python works good. But making it with TK is a bit hard.

    This is my unfinished code, i have tryed get() in many ways,.but I cant make it work. I´m only need to get knowledge about using get() now,.. I now there is other thing undone in this code.

    #
    import Tkinter
    from tkSimpleDialog import *
    import math
    import string

    def Add():
    xy = x + y


    def Sub():
    xy = x - y


    def Mul():
    xy = x * y


    def Div():
    xy = x / y


    root = Tkinter.Tk()

    x = Entry(root)
    x.grid(row=0, column=0, columnspan=2)

    y = Entry(root)
    y.grid(row=0, column=2, columnspan=2)

    text = Label(root, text="summa")
    text.grid(row=1 , column=0)

    Button(root, text='add', command=Add).gr id(row=2, column=0, columnspan=1)
    Button(root, text='sub', command=Sub).gr id(row=2, column=1, columnspan=1)
    Button(root, text='mul', command=Mul).gr id(row=2, column=2, columnspan=1)
    Button(root, text='div', command=Div).gr id(row=2, column=3, columnspan=1)

    root.mainloop()

      no morjesta :D

      use: Entry.get(x)
      and remember that the text field contains text, so you must convert it to numeric using float() (or double() for greater accuracy)

      [code=python]
      import Tkinter
      from tkSimpleDialog import *
      import math
      import string

      def Add():
      x1 = float(Entry.get (x))
      y1 = float(Entry.get (y))
      xy = x1 + y1
      print xy

      def Sub():
      x1 = float(Entry.get (x))
      y1 = float(Entry.get (y))
      xy = x1 - y1
      print xy

      def Mul():
      x1 = float(Entry.get (x))
      y1 = float(Entry.get (y))
      xy = x1 * y1
      print xy

      def Div():
      x1 = float(Entry.get (x))
      y1 = float(Entry.get (y))
      xy = x1 / y1
      print xy

      root = Tkinter.Tk()

      x = Entry(root)
      x.grid(row=0, column=0, columnspan=2)

      y = Entry(root)
      y.grid(row=0, column=2, columnspan=2)

      text = Label(root, text="summa")
      text.grid(row=1 , column=0)

      Button(root, text='add', command=Add).gr id(row=2, column=0, columnspan=1)
      Button(root, text='sub', command=Sub).gr id(row=2, column=1, columnspan=1)
      Button(root, text='mul', command=Mul).gr id(row=2, column=2, columnspan=1)
      Button(root, text='div', command=Div).gr id(row=2, column=3, columnspan=1)

      root.mainloop()
      [/code]
