Actually, it is not good idea to put so big part of code in try block and catch base exception. Also python has a name convention, so local variables should be like var_name, not CamelCase.

I am a beginner at python.

This script works at its basic function, but some choices generate errors. For my learning i have made a new script which catches errors, gives the ability to continue

import random
import sys
import re
import os
from distutils.util import strtobool

def user_yes_no_query(question):
    sys.stdout.write('%s [y/n]\n' % question)
    while True:
        try:
            return strtobool(raw_input().lower())
        except ValueError:
            sys.stdout.write('Please respond with \'y\' or \'n\'.\n')


cont = 1

#y = user_yes_no_query('do you want to play a game where you guess the number from 1 to 100 in 10 tries y/n');


while cont != 0:
    os.system('clear')
    NumOfTry = 10
    y = user_yes_no_query('do you want to play a game where you guess the number from 1 to 100 in 10 tries y/n');
    if y == 1:
        print ("yes")
        NumToGuess = random.randint(1, 100)
        print ('Try to guess a number between 1 and 100 in 10 tries ')
        while NumOfTry != 0:
            try:
                x = int (input ('Please enter a number between 1 and 100  '))
                if x > NumToGuess:
