Changing List Entry Syntax

I have a program that creates a small GUI for a function. In particular, I have something like this:

def create_widgets(self):
    self.entryLabel = Label(self, text="Please enter a list of numbers:")
    self.entryLabel.grid(row=0, column=0, columnspan=2)      

    self.listEntry = Entry(self)
    self.listEntry.grid(row=0, column=2, sticky=E)

    self.entryLabel = Label(self, text="Please enter an index value:")
    self.entryLabel.grid(row=1, column=0, columnspan=2, sticky=E)

    self.indexEntry = Entry(self)
    self.indexEntry.grid(row=1, column=2)

    self.runBttn = Button(self, text="Run Function", command=self.Function)
    self.runBttn.grid(row=2, column=0, sticky=W)

    self.answerLabel = Label(self, text="Output List:")
    self.answerLabel.grid(row=2, column=1, sticky=W)

Then for the definition of the function I have a part afterwards:

    self.answer = Label(self, text=rtn)
    self.answer.grid(row=2, column=2, sticky=W)

that tells it what to give as output.

Now, the issue is the input is entered as a string (say 12345) and so it would recognize the numbers 10,11,12 and so on as their individual digits. Is there a simple way to modify this to require list inputs to be comma delimited (e.g. 1,2,3,4,5)?

Thanks in advance.

If you are just asking how to turn "1,2,3,4,5" into a list of integers, you can do it with split and int.

user_input = "4,8,15,16,23,42"
numbers = [int(d) for d in user_input.split(",")]

print "numbers:", numbers
print "sum of numbers:", sum(numbers)

Result:

numbers: [4, 8, 15, 16, 23, 42]
sum of numbers: 108
