Types are not associated with expressions in Python: evaluating an expression produces a typed value, whose type, and not only its value, depends on the type and/or values of the inputs. Example:
def comparativeInsult(a,b):
if b>a:
return "try again"
if a>b:
return a/b
else:
return None
The type is, for all practical purposes, a part of the value of a Python object.
