This sets the password once, outside the loop.

> #password loop
> while Enter_Password != password:
>     if Enter_Password !=password:
>         print 'try again'
>     else:

This loops forever, but never asks for a password. You need to ask for a 
password *inside* the loop.

actual_password = 'route9999'
given_password = ''
while given_password != actual_password:
     given_password = raw_input('please enter your password: ')
     if given_password == actual_password:
         print 'well done'
         print 'try again'
