Yes, but there is valid syntax for the common case you mentioned:
y = x = 3
What you can't do (that I really miss) is have a tree of assign-and-test
expressions:
import re
pat = re.compile('some pattern')
if m = pat.match(some_string):
do_something(m)
else if m = pat.match(other_string):
do_other_thing(m)
else:
do_default_thing()
