类方法getter-Python出错

我在获取电话号码的方法getter方面遇到了一点问题。这是我的代码：

# Personal info class
class PersonalInfo:
    def set_names(self, name):
        self.__names = name

    def set_addresses(self, add):
        self.__addresses = add

    def set_ages(self, age):
        self.__ages = age

    def set_numbers(self, number):
        self.__numbers = number

    # Accessor methods    
    def get_names(self):
        return self.__names

    def get_addresses(self):
        return self.__addresses

    def get_ages(self):
        return self.__ages

    def get_numbers(self):
        return self.__numbers

def main():
    # references PersonalInfo object
    info = PersonalInfo()

    # stores values in the object
    info.set_names("Will")
    info.set_addresses("26 Explorer Blvd, Punta Gorda, FL")
    info.set_ages("21")
    info.set_numbers("941-245-0255")

    # displays values stored in object's fields
    print "Name:", info.get_names()
    print "Address:", info.get_addresses()
    print "Age:", info.get_ages()
    print "Phone number:", info.get_numbers
    print

    # stores new values
    info.set_names("Pat")
    info.set_addresses("26 Explorer, Punta Gorda, FL")
    info.set_ages("28")
    info.set_numbers("941-245-0266")

    # displays new values
    print "Name:", info.get_names()
    print "Address:", info.get_addresses()
    print "Age:", info.get_ages()
    print "Phone number:", info.get_numbers
    print 

    # stores new values again
    info.set_names("Motley")
    info.set_addresses("11 Scotland Ave, Edison, NJ")
    info.set_ages("49")
    info.set_numbers("732-709-3409")

    # displays newest values
    print "Name:", info.get_names()
    print "Address:", info.get_addresses()
    print "Age:", info.get_ages()
    print "Phone number:", info.get_numbers

main()

当我运行此代码时，对于所有电话号码，它显示“main.PersonalInfo instance at 0x0297BB70>>”。这是一堂计算机编程入门课，我真的不明白我哪里出错了。任何帮助都将不胜感激。：）

您忘记实际调用该方法。请注意以下要点：

print "Phone number:", info.get_numbers()

首先，同样，开头的双下划线是不好的。如果您需要询问是否需要使用它们，那么您不需要使用它们。不要使用getter和setter。我建议你读一下这篇文章，它会为你节省很多时间和精力。
