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
above line
                                   # also you can use count += 1 instead
	else:
		print "Password Confirmed"
		# to exit you can use the exit() function
