Python编写Employee类打印员工信息遇ModuleNotFoundError求助

核心问题分析 #

1. 模块导入错误：未按要求将代码拆分为employee.py和employee_test.py两个独立文件，导致导入时找不到employee模块。
2. 代码语法错误：原代码存在类定义缺冒号、方法未缩进、f-string格式错误等问题。

修正步骤及代码 #

第一步：创建employee.py文件 #

将Employee类代码单独存放，修正语法错误：

class Employee:
    def __init__(self, name, id_num, dep, title):
        self.__name = name
        self.__id = id_num
        self.__dep = dep
        self.__title = title

    def set_id(self, id_num):
        self.__id = id_num

    def set_dep(self, dep):
        self.__dep = dep

    def set_title(self, title):
        self.__title = title

    def __str__(self):
        result = f"{self.__name}\t{self.__id}\t{self.__dep}\t{self.__title}"
        return result

修正点：

• 类定义添加冒号class Employee:
• 所有类方法缩进至类内部
• __str__方法中修正属性引用（self__name→self.__name），将/t改为制表符转义字符\t，修复f-string格式

第二步：创建employee_test.py文件 #

将测试代码单独存放，确保和employee.py在同一目录下：

from employee import Employee 

def main():
    Susan = Employee("Susan Meyers", "47899", "Accounting", "Vice President")
    Mark = Employee("Mark Jones", "39119", "IT", "Programmer")
    Joy = Employee("Joy Rogers", "81774", "Manufacturing", "Engineer")

    print(Susan)
    print(Mark)
    print(Joy)

main()

运行结果 #

执行employee_test.py后，输出如下：

Susan Meyers	47899	Accounting	Vice President
Mark Jones	39119	IT	Programmer
Joy Rogers	81774	Manufacturing	Engineer
