## Code Snippet

``````import sys
#Analyse the nature of the boolean flag, tries variable and WHILE LOOP USED BELOW
#CREATE a question inside of the quiz function. Give the user 2 tries to get the answer right, else out they go!
def main():
tries=0 #this is a variable called tries set to start at 0 (initialised at zero)
accessgranted=False #this is a boolean variable that is set to False. The other option is that it can be True!
while accessgranted == False and tries<3: #while access granted is equal to False and the tries is less than 3....
print("Access Granted")
accessgranted=True #if the password is right, then change this variable to TRUE and exit loop
quiz()
else:
print("Denied")
tries=tries+1 #for each time it is not true increase the variable 'tries' by +1
if tries>=3: #finally, if tries is equal to or greater than 3, then kick the user off! They're an impostor!
print("Sorry, you have exceeded the number of tries. Goodbye")

def  quiz():
print("****************WELCOME***********************")
print("The wonderful world of learning python awaits .....")
