如果不放init()中，每次都会初始化count，count得不到修改

#1 Created at ... [Delete] [Delete and Lock User]

class Student(object):

    count = 0

    def __init__(self, name):

        self.name = name

        Student.count += 1

~\(≧▽≦)/~

#2 Created at ... [Delete] [Delete and Lock User]

为什么不能写成 self.count+=1 呢？

梦如丨方初醒

#3 Created at ... [Delete] [Delete and Lock User]

写成self.count += 1的话，每创建一个实例对象，类属性count会被重置为0
