Help me with phthon GUI.

I have a template provided by professor. I need to complete it.

I will give you a template, so copy and paste into your python file:

--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

from tkinter import *
from tkinter.font import *
from tkinter.ttk import *
from tkinter import *

# the template code generates the top frame on the GUI
# and the bottom frame. The top frame contains the Entry
# object and the "Send" key. If the Entry key is double-clicked,
# the Entry object is cleared.

# I've also set up a "letters" variable to reflect the relative positions
# of letters on a keyboard. The first row ['q','w','e',...] is letters[0].
# Note that since letters is a 2-dimensional list, letters[0] is also a list.

# This organization may help you set up frames, one for each row on the keyboard.
class Phone:
     def __init__(self):
          window = Tk()

          # self.buttons is a dictionary; Key in this dictionary are
          # Button objects. An entry's value is the label on that button.
          self.buttons = dict()

          # Here are the letters as they will be laid out on the
          # keyboard. Notice this is a 2-dimensional list. The
          # rows in the list correspond to rows of keys (Buttons)
          # on the keyboard. For example, 'q' is the leftmost
          # letter on the first row (below the Entry object) and
          # 'p' is the rightmost; 'a' is the leftmost letter on the
          # next row, etc. '<' is meant to be the backspace key.
          letters = [['q','w','e','r','t','y','u','i','o','p'],
                     ['a','s','d','f','g','h','j','k','l'],
                     ['z','x','c','v','b','n','m','<']]

          # a StringVar is a mutable string
          # "msg" is a StringVar that is displayed on the Entry called "e"
          self.msg = StringVar()

          # This frame holds e, plus the "Send" key
          f = Frame(window)
          f.pack()
          self.e = Entry(f,textvar=self.msg) #,justify='right')
          # columnspan=6 makes the Entry wide
          self.e.grid(row=0,column=0,columnspan=6,sticky=N+S+E+W)
          # The "Send" key is next to the Entry
          b = Button(f,text='Send',font=Font(family='Arial',size=6))
          b.grid(row=0,column=6)
          #############################################
          # Set up the event handler for the send key
          # Just requires one line of code
          #############################################

          ###################################################
          # Write the code that places 26 Buttons
          # on the GUI, one for each letter, with the
          # layout corresponding to the "letters" variable
          # above. To do this, place create a separate Frame
          # for each row of Buttons on the keyboard, and then
          # pack each Frame into the Tk window.
          ###################################################

        

          ###################################################
          # Below, I've provided the code to set up the space
          # key and the '.' key next to it
          # The space key has no label on it.
          ###################################################
          f = Frame(window)
          space = Button(f,width=10)
          # columnspan is used to make the space key larger
          space.grid(row=0,column=0,columnspan=3)
          self.buttons[space] = ' '
          # Here is the '.' key
          dot = Button(f,text='.')
          self.buttons[dot] = '.'
          dot.grid(row=0,column=3)
          ###################################################
          # Set up event-handlers for the space and dot keys.
          # You can probably use the same event-handler
          # as for the letter keys.
          ###################################################

        
          f.pack()

     ######################################################
     # Below, write the event-handling code for the various
     # buttons.
     ######################################################
     def type(self, event):
          pass

Your assignment is to write a Python class that displays a GUI that looks like a computer keyboard, or one that is displayed by a cell phone in texting mode. At the top, there is a tkinter Entry object which displays the sequence of clicks that the user has made. There is also a "Send" button (which obviously does not send anything) tk Send The GUI should behave as follows: 1. when a key (other than the or the Send key) is clicked (left click), the corresponding letter/symbol is added to the Entry. For example, after clicking 'hi and the display should look like this: tk hi Send

Explanation / Answer

python 2.7.12 version

import sys
import Tkinter
from Tkinter import *

Keyboard_app=Tkinter.Tk()
Keyboard_app.title("Keyboard")
Keyboard_app.resizable(0,0)

def select(value):
if value == "<-":
entry2 = entry.get()
pos = entry2.find(' ')
pos2 = entry2[pos:]
entry.delete(pos2,Tkinter.END)
elif value == "Space":
entry.insert(Tkinter.END,' ')
elif value == "Tab":
entry.insert(Tkinter.END,' ')
else:
entry.insert(Tkinter.END,value)

buttons = [
'q','w','e','r','t','y','u','i','o','p',
'a','s','d','f','g','h','j','k','l',
'z','x','c','v','b','n','m','Space','Tab','<-','.'
]

label1 = Label(Keyboard_app,text='').grid(row=0,column = 1)
entry = Entry(Keyboard_app, width = 80)
entry.grid(row = 1, columnspan = 15)

varRow = 2
varColumn = 0

for button in buttons:
command = lambda x=button:select(x)
if button != "Space":
Tkinter.Button(Keyboard_app,text = button,width = 5,bg="#0000ff",fg="#ffffff",
activebackground = "#ffffff", activeforeground="#000000",relief='raised',padx=4,
pady=4,bd=4,command=command).grid(row = varRow,column = varColumn)
if button == "Space":
Tkinter.Button(Keyboard_app,text = button,width = 60,bg="#0000ff",fg="#ffffff",
activebackground = "#ffffff", activeforeground="#000000",relief='raised',padx=4,
pady=4,bd=4,command=command).grid(row = 6,columnspan = 16)
  
varColumn = varColumn + 1
if varColumn > 14 and varRow == 2:
varColumn = 0
varRow = varRow + 1
if varColumn > 14 and varRow==3:
carColumn = 0
varRow = varRow + 1

Keyboard_app.mainloop()
