Parameter Markers not working as expected

hi,

I am trying to use simple parameter marker to read password from the user. Below one liner is throwing error.

password = input("Please enter your password here", hidden = True)

--> [error] TypeError ( input() got an unexpected keyword argument 'hidden' )

Similarly below is not working either.

items = ("nothing selected", "item1", "item2", "item3")
selected = select ("Please select an item from the list", options = items)
if selected == items[0]:
   popup("You did not select an item")
   exit(1)
--> [error] NameError ( name 'select' is not defined )

Can someone please help.
