Now, let’s make a mode to cook dinner our scorching puppy: def cook(self, time): raises the self. cooked_level = self. cooked_level + time cooked point through the if self. cooked_level > eight: period of time self. cooked_string = "Charcoal" elif self. cooked_level > five: units the strings self. cooked_string = "Well-done" for different elif self. cooked_level > three: cooked degrees self. cooked_string = "Medium" else: self. cooked_string = "Raw" prior to we cross any longer, let’s attempt this half. First, we have to create an example of a scorching puppy, and we’ll cost the attributes, too.

Directory thirteen. 2 Passing a controversy to a functionality def printMyAddress(myName): print myName Prints the identify print "123 major highway" print "Ottawa, Ontario", Canada print "K2M 2E9" print printMyAddress("Carter Sande") Passes myName argument to the functionality Passes “Carter Sande” because the argument to the functionality; the variable myName contained in the functionality may have the price “Carter Sande” If we run the code in directory thirteen. 2, we get precisely what you’d count on: >>> ===================== RESTART ===================== >>> Carter Sande 123 major road Ottawa, Ontario, Canada K2M 2E9 >>> authorized to Deborah Christiansen
