Answer 1

In Python, a distinction between expressions and statements is rigidly enforced, in contrast to languages such as Common Lisp, Scheme, or Ruby.

So by introducing such operators, you would break the expression/statement split.

For the same reason you can't write

if x = 0:
  y = 1

as you can in some other languages where such distinction is not preserved.
