Suppose you have:

     x or y

If bool(x) returns True, then the result will be x, else the result will 
be y.

Example 1:

bool("String1") returns True, therefore the result of:

     "String1" or "String2"

is "String1".

Example 2:

bool("") returns False, so the result of:

     "" or "String2"

is "String2".

(The empty string "" is considered 'false-y'; all other strings (i.e. 
all non-empty strings) are considered 'true-y'.)
