regarding the `consider-ternary-expression`

    if condition():
       x = 4
    else:
       x = 5

    x = 4 if condition() else 5

regarding the `while-used`, while I personally prefer the legibility of the `for` loop, I find the following paragraph... at best wrong:

>>> A while loop introduces unbounded computation. Do you really need unbounded computation for your boring web app? I doubt it. In almost all cases, the loop can be bounded in advance, as in “do this N times” or “do this for every item in this list”. Those kinds of loops are guaranteed to terminate, and that’s a nice guarantee to have.

in python `for` loop are equally unbounded as `while` ones. Yes, most of the time you are looping over a (finite) list or a (finite) dict, but the concept underlying the `for` loop is the iterator, not the list. And iterators can easily be infinite.
