Need help in identifying the mistake in my code. Tkinter messagebox not displaying desired output

def play():

break
if ans[i] == selected:
print("Correct Answer")

score = len(user_ans)*10

qsn = tk.Label(wind2)
r1 = tk.Radiobutton(wind2, variable = v, value = 1, command=selection)
r2 = tk.Radiobutton(wind2, variable = v, value = 2, command=selection)
r3 = tk.Radiobutton(wind2, variable = v, value = 3, command=selection)
r4 = tk.Radiobutton(wind2, variable = v, value = 4, command=selection)
nbut = tk.Button(wind2, text = "next", command = nxt)
After selecting the correct option, (i.e. when ans[i]=selected) the length of user_ans is of course not 0. Then why does the messagebox return score as 0 everytime? I am unable to figure out if I have made any mistake.
Basically this is a quiz application. Score of the user is 10 times the number of correct answers.

First, please provide a reproducible code sample next time. There are a lot of logic errors in your script. First you calculate your score in the beginning when you run the play function. At that point your list user_ans is still empty. If you move your score calculation into the nxt function, you end up with different issues, for example your score can go into infinity when someone keeps clicking the right answer over and over. So you should evaluate the user selection only once the user clicks next.
Here is some rearrangement. Still this is not ideal, but you can work from there.

How to implement client/server (sockets) to two player boggle game

Here is the code I currently have. The program works great I just want to make the game playable using sockets.

Python Tkinter - Deleting an item from a list when I don't know its index

I'm new to python and I am currently learning for loops in Tkinter and trying to build pin code GUI.
What I want to happen is when the back space button is pressed "<" the last item added to the list "Entered Pin" is removed and 1 Asterix is removed from TxtWindow? I'm wondering if there is a particular way in python to remove the last item added to a list when I am unaware how many items there will be in the list.
Thanks in advance my code is below
import tkinter as tk
window = tk.Tk()
def PinEntry(x):
global u
global counter
if u == 1:
TxtWindow.delete("1.0", "end")
u = u+1
if EntertedPin == DefaultPin:
window.destroy()
if x in range (len(EntryKeyList)):
EntertedPin.append (EntryKeyList [x])
TxtWindow.insert (tk.END, "*")
counter = counter +1
if x == 2:
EntertedPin.clear()
TxtWindow.delete("1.0", "end")
TxtWindow.insert (tk.END, "Enter Pin")
u = 1
coutner = 0
if x == 0:
EntertedPin.clear()
TxtWindow.delete("1.0", "end")
TxtWindow.insert (tk.END, "Enter Pin")
u = 1
counter = 0
if x == 12:
# Delete last number in the list and remove one asterix from the TxtWindow
EntertedPin = []
DefaultPin = [1,2,3,0]
u = 1
counter = -1
TxtWindow = tk.Text(window, relief = "sunken", width = 10, height = 1)
TxtWindow.insert (tk.END, "Enter Pin")
TxtWindow.grid (row = 1, column = 2)
x = 1
y = 1
a = 5
b = 4
c = 1
d = 3
e = 1
f = 2
g = 1
EntryKeyList = ["CLR", 0, "ENT", 1, 2, 3, 4, 5, 6, 7, 8, 9, "<" ]
for i in range (13):
KeypadBtn = tk.Button(window, width = 5, height = 3, text = EntryKeyList[i], command = lambda x=i: PinEntry(x))
if y <=3:
KeypadBtn.grid (row = a , column = x )
x = x +1
y=y +1
elif y <= 6:
KeypadBtn.grid (row = b , column = c )
c = c +1
y=y+1
elif y <= 9:
KeypadBtn.grid (row = d , column = e )
e = e +1
y=y+1
elif y <=12:
KeypadBtn.grid (row = f , column = g )
g = g +1
y=y+1
else:
KeypadBtn.grid (row = 1, column = 3)
window.mainloop()

The commands what you are looking for
TxtWindow.delete("end-2c", "end")
mylist=mylist[:-1] or mylist.pop()
But the code is wrong. The backspace cannot add "x" to widget.
def PinEntry(x):
global u
global counter
global EntertedPin
global DefaultPin
if u == 1:
TxtWindow.delete("1.0", "end")
u = u+1
if x in range (len(EntryKeyList)):
if x == 12:
# Delete last number in the list and remove one asterix from the TxtWindow
EntertedPin=EntertedPin[:-1]
TxtWindow.delete("end-2c", "end")
# If the button is not number:
else:
if x == 2:
EntertedPin.clear()
TxtWindow.delete("1.0", "end")
TxtWindow.insert (tk.END, "Enter Pin")
u = 1
coutner = 0
elif x == 0:
EntertedPin.clear()
TxtWindow.delete("1.0", "end")
TxtWindow.insert (tk.END, "Enter Pin")
u = 1
counter = 0
EntertedPin.append (EntryKeyList [x])
TxtWindow.insert (tk.END, "*")
counter = counter +1
if EntertedPin == DefaultPin:
window.destroy()

how to solve the print string error on python eclipse

I am not sure why do i get this error from the console:
<<
print stirngp[state[i][j]]
^
SyntaxError: invalid syntax

Furthermore it seems that the IDE put a red close on the following code line
line = raw_input("Enter:")
I am not sure what did i do wrong, the following code is as shown below

As far as i know you can't use raw_input() in Python 3. It's been changed to just input()
http://docs.python.org/dev/whatsnew/3.0.html
also what is stringp? is it an existing list?
if so then state[i][j] MUST return an integer so you can retrieve the item at that index of stringp[]

How do I print these return values from function in Python 3?

I have a homework assignment for raquetball simulation. I'm trying to figure out how to expand the program to account for shutouts and return the number for each player. I added a loop into the simNGames() to count the shutouts. I'd like to return those values and print them out in the summary.
def simNGames(n, probA, probB):
winsA = 0
winsB = 0
shutoutA = 0
shutoutB = 0
for i in range(n):
scoreA, scoreB = simOneGame(probA, probB)
if scoreA > scoreB:
winsA = winsA + 1
else:
winsB = winsB + 1
for i in range(n):
scoreA, scoreB = simOneGame(probA, probB)
if scoreA == 15 and scoreB == 0:
shutoutA = shutoutA + 1
if scoreA == 0 and scoreB == 15:
shutoutB = shutoutB + 1
return winsA, winsB, shutoutA, shutoutB ## The program breaks when I add
## shutoutA, and shutoutB as return val
If anyone could steer me in the right direction It'd be greatly appreciated. I get a ValueError: too many values to unpack (expected 2), when I add shutouts into the return value. Here is the entire program:
from random import random
def main():
probA, probB, n = GetInputs()
winsA, winsB = simNGames(n, probA, probB)
PrintSummary(winsA, winsB)
def GetInputs():
a = eval(input("What is the probability player A wins the serve? "))
b = eval(input("What is the probablity player B wins the serve? "))
n = eval(input("How many games are they playing? "))
return a, b, n
def simNGames(n, probA, probB):
winsA = 0
winsB = 0
shutoutA = 0
shutoutB = 0
for i in range(n):
scoreA, scoreB = simOneGame(probA, probB)
if scoreA > scoreB:
winsA = winsA + 1
else:
winsB = winsB + 1
for i in range(n):
scoreA, scoreB = simOneGame(probA, probB)
if scoreA == 15 and scoreB == 0:
shutoutA = shutoutA + 1
if scoreA == 0 and scoreB == 15:
shutoutB = shutoutB + 1
return winsA, winsB
def simOneGame(probA, probB):
serving = "A"
scoreA = 0
scoreB = 0
while not gameOver(scoreA, scoreB):
if serving == "A":
if random() < probA:
scoreA = scoreA + 1
else:
serving = "B"
else:
if random() < probB:
scoreB = scoreB + 1
else:
serving = "A"
return scoreA, scoreB
def gameOver(a, b):
return a == 15 or b == 15
def PrintSummary(winsA, winsB):
n = winsA + winsB
print("\nGames simulated:", n)
print("Wins for A: {0} ({1:0.1%})".format(winsA, winsA/n))
print("Wins for B: {0} ({1:0.1%})".format(winsB, winsB/n))
if __name__ == '__main__': main()

When you call the function:
winsA, winsB = simNGames(n, probA, probB)
You're expecting only two values (winsA, winsB), but returning four.
