Hello daniel, some comments
password = "qwerty"
guess = "0" # <- no need to initialise that variable or
# if you would need, using just "" would be enough #instead of "0"
count = 0
while count != 3: # <- that works here, but i usually use "< 3"
guess = raw_input("Enter your password: ")
guess = str(guess) # no need to typecast here because
raw_input alredy returns a str
#when you don't know the type use
type(yourvar) in python
if guess != password # missing ":"
print "Access Denied"
count = count + 1 # <- has to be indented to the same level with the
# also you can use count += 1 instead
print "Password Confirmed"
# to exit you can use the exit() function
