AttributeError:“列表"对象在python中没有属性“显示" [英] AttributeError: 'list' object has no attribute 'display' in python

问题描述

当我使用类对象调用显示函数时出现错误 我该怎么做才能克服这个问题?

Error comes when i call the display function using class object What should i do to overcome this ??

class A:

    def __init__(self, fname, lname, age):
        self.fname = fname
        self.lname = lname
        self.age = age

    def disply(self):
        fp = open("abc","r")

        for lines in fp:
            temp = lines.split(", ")[-1]
        fp.close()

        print a

a = [A("Taylor","Launter",22), A("James","bond",40)]
a.display()

推荐答案

a = [A("Taylor","Launter",22), A("James","bond",40)]
a.display()

现在a是一个列表. python中的列表没有display方法.

Now a is a list. Lists in python dont have display method.

您可能真正想做的是调用A对象的display方法.如果是这样，您可能想做这样的事情

What you might actually have wanted to do is to invoke display method of the object of A. If that is the case, you might want to do something like this

for currentObject in [A("Taylor","Launter",22), A("James","bond",40)]:
    currentObject.display()

编辑您的display方法对我来说没有任何意义.

Edit Your display method doesnt make any sense to me.
