I did specifically say "easier to learn and teach" instead of using generic phrases such as "simpler" or "harder to understand". You won't make Python easier to learn and teach by adding a new assignment syntax, since people will have to learn the old form as well. Having to break things out over multiple lines is a fact of life, if only for readability when implementing (and maintaining!) non-trivial processing routines. It's a good thing to be used to it, and to learn to choose good names for intermediate variables.
