Good code patterns in Python

One, there has been a proposal for a ternary operator on python.org. You
know that kind of  (cond) ? (eval1) : (eval2) stuff.

Two, no need to guard that code. Passing and assigning a paramater should
always make you THINK about what's happening.

Three, how about
a = 1
b = 0
.....
if b == 0:
  a = 0
else:
  a = a/b
? You cannot replace it with your pattern. Sure enough, there are far more
examples of this -- when you cannot evaluate the first expression.
