Trinary operator?

[Christophe Delord]

You have to be very carefull with and/or. If you evaluate A and B or C, if A is true and B is false, the result is C !!!

For example, "number=='zero' and 0 or 1" returns 1 whatever the value of number

>>> number='one'
>>> number=='zero' and 0 or 1
1
>>> number='zero'
>>> number=='zero' and 0 or 1
1
>>>
