I could care less about the curly braces and commas.  The central idea 
is an n-ary choice, presented in logical order, surrounded by grouping 
delimiters that the parser can easily recognize, with no new keyword. 
Any of these would do:

t = (if "spam" not in s: "customer", "eggs" in s: "vikings", "waitress")
t = (if "spam" not in s: "customer"
      elif "eggs" in s: "vikings"
      else: "waitress")
t = if:("spam" not in s,  "customer",
         "eggs" in s, "vikings",
         "waitress")
