help with python script

[The-ITu]

here is the code:


import os from Tkinter import * def cls(): os.system(['clear', 'cls'][os.name=='nt']) print 'This is a Tk button creater!' raw_input("press enter to continue") cls() amountOfButtons = input("how many buttons do you want? (max 10) >>> ") amountOfButtons = amountOfButtons + 1 tkTitle = raw_input('what would you like the title of the canvas to be? >>> ') while amountOfButtons > 10: print "that is an in correct value." amountOfButtons = input("how many buttons do you want? (max 10) >>> ") command1, command2, command3, command4, command5, command6, command7, command8, command9, command10 = ' ', ' ', ' ', ' ', ' ', ' ', ' ', ' ', ' ', ' ' listOfComands = [command1, command2, command3, command4, command5, command6, command7, command8, command9, command10] text1, text2, text3, text4, text5, text6, text7, buton8, text9, text10 = ' ', ' ', ' ', ' ', ' ', ' ', ' ', ' ', ' ', ' ' listOfButtonComands = [text1, text2, text3, text4, text5, text6, text7, buton8, text9, text10] for x in range (1, amountOfButtons): rv = str(x) listOfComands[x] = raw_input("what do you want button %s to to have writen on it? >>> " % rv) for i in range (1, amountOfButtons): rvi = str(i) listOfButtonComands[i] = raw_input("what do you want button %s to return >>> " % rvi) def pnt(num): print listOfButtonComands[num] canvasHeight = input("how high do you want your canvas? >>> ") canvasWidth = input("how wide do you want your canvas? >>> ") cls() raw_input("press enter to create!!") cls() root = Tk() root.title(tkTitle) canvas = Canvas(root, height=canvasHeight, width=canvasWidth) canvas.pack() for g in range (1, amountOfButtons): btn = Button(root, text = listOfButtonComands[g], command = pnt(g)) btn.pack() raw_input()now the problem is in line 17 and 18 where im trying to make a list of empty variables but it tell me that they are not defined. how can i get past this?is

Well, you could assign the variables before you use them.
It would look ugly, but you could assign all variables to the value None.
E.x. command1, command2, ... = None

To create the desired commands list you can do this as well:

listOfCommands = []
for x in range (0, amountOfButtons):
listOfCommands.append(raw_input("what do you want button %s to to have writen on it? >>> " % x) )
# for debugging print content of listOfCommands
print listOfCommands

In this way you don't limit yourself to a maximum number of elements in the list, as the append method appends items to the list. Also note the correction in the way you make the prompt for raw_input.

About the Tkinter part of your code: you need to create a root widget, to which you add child windows, e.g.

root = Tk()

canvas = Canvas(root, height=canvasHeight, width=canvasWidth)
canvas.pack()

for g in range (0, amountOfButtons):
btn = Button(root, text = listOfCommands[g], command = pnt(g))
btn.pack()
