The "while" loop is saying: get input from the user, and as long as the
response does NOT equal "unicorn", keep looping.
You can't check the value of a variable that doesn't exist yet, so the line
'password = "foobar" ' merely served to to create/initialize the 'password'
variable. Faced with a similar situation, I would have said ' password = ""
' to avoid exactly this sort of confusion. In fact, I would have done
something like the following:
tmp_str = "" # this creates the variable so we can check against its value
later on
password = "unicorn"
while tmp_str != password:
tmp_str =raw_input("Password: ")
print "Welcome in"
I hope that makes things a bit clearer...
