Question

只是想打印红色和蓝色-

class color:
    def __init__(self,r,b):
        self.r = r
        self.b = b

        def displaycolor(self):
            print "The first should be :" self.r
            print "The 2nd should be :" self.b
pagal=color("Red","blue")
pagal.displaycolor()

Answer 1

两个问题：打印时的标识和字符串连接：

class color:
    def __init__(self,r,b):
        self.r = r
        self.b = b

    def displaycolor(self):
        print "The first should be :", self.r
        print "The 2nd should be :", self.b
pagal=color("Red","blue")
pagal.displaycolor()
