Ordering of Conditions There is an issue with multiway decision structures that does not exist with one or two- way if statements. The order in which the conditions appear in a multiway if statement is important. To see this, try to figure out what is wrong with the order of the conditions in the next implementation of the function temperature(). def temperature(t): if t > 32: print('It is cool.) elif t > 86: print('It is hot!') else: print('It is freezing!') The problem with this implementation is that 'It is cool' will be printed for all values of t greater than 32. So, if t is 104, what is printed is 'It is cool.'. In fact. 'It is hot!' will never get printed, no matter how high the value of t is. The issue is that conditions t > 32 and t > 86 are not mutually exclusive, as conditions corresponding to code blocks in a two-way decision structure are. One way to fix the wrong implementation is to make the conditions mutually exclusive explicitly: def temperature(t): if 32 86: print('It is hot!') else: t 86, 32 86. Any subsequent condition in a three-way if statement will be tested only if the first condition fails (i.e., the value of t is no more than 86). Therefore, any subsequent condition includes, implicitly, condition t 32 is really 32
