Question

I have been googling about this problem and couldn’t find any good websites….
I want to create buttons and entry widget looks like:

[A] [B] [C] [D] [E] [F]

[ENTRYWIDGET HERE] [OK]

My code looks like:

class Controller(Frame):

def __init__(self,parent):
    Frame.__init__(self, parent)
    self.parent = parent
    self.button1 = Button(parent, text = "A")
    self.button1.pack(side = TOP)
    self.button1 = Button(parent, text = "B")
    self.button1.pack(side = TOP)
    self.button1 = Button(parent, text = "C")
    self.button1.pack(side = TOP)
    self.button1 = Button(parent, text = "D")
    self.button1.pack(side = TOP)
    self.button1 = Button(parent, text = "E")
    self.button1.pack(side = TOP)
    self.button1 = Button(parent, text = "F")
    self.button1.pack(side = TOP)

    self.myentrybox = Entry(parent, width = 50)
    self.myentrybox.pack(side = LEFT)
    self.button = Button(parent, text = "OK")
    self.button.pack(side = RIGHT )

And this looks completely different with what i’m trying to create..

Any feedbacks would be so grateful thanks.

You can just put your buttons into another Frame.

Example:

from Tkinter import *
from ttk import *

class Controller(Frame):

    def __init__(self,parent):
        Frame.__init__(self, parent)

        buttons = Frame(parent)
        buttons.pack(side=TOP)
        for letter in 'ABCDEF':
            Button(buttons, text=letter).pack(side=LEFT)

        Entry(parent, width=50).pack(side=LEFT)
        Button(parent, text='OK').pack(side=RIGHT)

root = Tk()
app = Controller(root)
root.mainloop()

Result:

Edit to answer your comments

If you want to stick with for loop for creating the buttons, a good way to apply the event handler is to create a mapping of button <=> function to call using a dict:

    handler = {'A': function_A,
               'B': function_FooBar,
               'C': function_SomeThing}

    for letter, func in ((k, handler[k]) for k in sorted(handler)):
        Button(buttons, text=letter, command=func, width=10).pack(side=LEFT)

This way, it’s easily extendable. If you don’t care about the order of the buttons, you can just use

for letter, func in handler.items():
