Question

我想通过printPerson使用x和y来打印，但是我无法解决此问题。当我尝试使用x.printPerson时，它指出未定义printPerson。怎么来的？

class Person:
    def __init__ (self, name, age, strong, vehicle):
        self.name = name
        self.age = age
        self.strong = strong
        self.vehicle = vehicle

    def printPerson(self):
        print("Name:" + self.name)
        print("Age:" + self.age)
        print("Strong:" + self.strong)
        print("Vehicle:" + self.vehicle)            

x = Person("x", 20, ["Strong", "Strong", "Strong"], ["Car" , "Bike"])
y = Person("y",21, ["Weak", "Weak", "Super weak"], ["bus", "tractor"])

如何打印x输出如下：

>>> x.printPerson()

Name: x
Age: 20
Strong: "Strong, Strong, Strong"
Vehicle: "Car, Bike"

Answer 1

尝试：

x.printPerson()

而不是：

x.printPerson

完整代码：

class Person(object):
    def __init__ (self, name, age, strong, vehicle):
        self.name = name
        self.age = age
        self.strong = strong
        self.vehicle = vehicle

    def printPerson(self):
        print("Name:" + self.name)
        print("Age:" + str(self.age))
        print("Strong:" + ", ".join([val for val in self.strong]))
        print("Vehicle:" + ", ".join([val for val in self.vehicle]))

x = Person("x", 20, ["Strong", "Strong", "Strong"], ["Car" , "Bike"])

x.printPerson()
