Question

好吧，我研究了很多帖子，但没有一个让我修复我的代码。

我正在学习python，目前正在学习面向对象的课程。

这是我的代码： -

class Employee:
    'Common base calss for all employees'
    empCount = 0

    def __init__(self,name,salary):
        self.name = name
        self.salary = salary
        Employee.empCount += 1

    def displayCount(self):
        print "Total Employee %d" % Employee.empCount

    def displayEmployee(self):
        print "Name: ", self.name, ",Salary: ", self.salary

"This whould create first object of Employee class"
emp1 = Employee("Zara", 2000)
"This whould create second object of employee class"
emp2 = Employee("Manni", 5000)

emp1.displayEmployee()
emp2.displayEmployee()
print "Total Employee %d" % Employee.empCount()

然后当我运行它时： -

Name:  Zara ,Salary:  2000
Name:  Manni ,Salary:  5000

Traceback (most recent call last):
File "D:/Python Programs/Object Oriented-Classes(Python 2).py", line 46, in 
<module>
print "Total Employee %d" % Employee.empCount()
TypeError: 'int' object is not callable

Answer 1

更改此

print "Total Employee %d" % Employee.empCount()

到这个

print "Total Employee %d" % Employee.empCount

Answer 2

查看错误。

TypeError : 'int' object is not callable

您正在尝试调用类变量Employee.empCount，这是一个整数，因此无法调用。

只需将其更改为Employee.empCount即可打印出变量。

Answer 3

您写了＆＃34; Employee.empCount（）＆＃34;。记住，＆＃34;（）＆＃34;这用于调用函数。就像你可以做的那样＆＃34; Employee.displayCount（）＆＃34;，因为displayCount（）是一个函数。但要访问变量，只需这样做：

print "Total Employee %d" % Employee.empCount

Python显示： - TypeError：'int'对象在python中不可调用而试图运行代码
