前言
halo！好久不见，很久没写博客，一直想要找回当初在学校里敲代码学习的状态，所以现在虽然做着简单枯燥的软测工作，但是也有开始学习python，下面就是最入门级的一个员工管理系统，算是对python基本语法学习完的交代。
代码
#员工管理系统
#定义一个员工信息字典
employee = {}
# 1、显示菜单
def show_menu():
print("*" * 30)
print("员工管理系统 v2.0")
print(" 1：添加员工信息")
print(" 2：删除员工信息")
print(" 3：编辑员工信息")
print(" 4：查看所有员工信息")
print(" 5：查看具体员工信息")
print(" 6：退出员工系统")
print("*" * 30)
# 2、显示所有信息
def show_all_info():
for em_number in employee:
# print(employee)
print("员工编号：" + em_number +
", 员工姓名：" + employee[em_number]['name'] +
", 员工薪水：" + employee[em_number]['salary'] +
", 员工性别：" + employee[em_number]['sex'])
#3、根据员工编号查看员工信息
def show_single_info():
em_number = input("请输入要查看的员工编号：")
em_name = employee[em_number]['name']
em_salary = employee[em_number]['salary']
em_sex = employee[em_number]['sex']
print("姓名：" + em_name + " 薪水：" + em_salary + " 性别：" + em_sex)
# 4、新增员工
def add():
em_number = input("请输入员工编号：")
em_name = input("请输入员工姓名：")
em_salary = input("请输入员工薪水：")
em_sex = input("请输入员工性别：")
em_info = {'name': em_name, 'salary': em_salary, 'sex': em_sex}
employee[em_number] = em_info
print("新增员工成功！请按4查看所有员工信息")
#5、编辑员工信息
def edit():
em_number = input("请输入员工编号：")
if em_number not in employee:
print("您输入的员工编号不存在！")
return
new_name = input("请输入新的员工姓名：")
new_salary = input("请输入新的员工薪水：")
new_sex = input("请输入新的员工性别：")
employee[em_number]['name'] = new_name
employee[em_number]['salary'] = new_salary
employee[em_number]['sex'] = new_sex
print("编辑员工编号为" + em_number + "的员工信息成功")
#6、删除员工
def delete():
em_number = input("请输入员工编号：")
if em_number not in employee:
print("您输入的员工编号不存在！")
return
del employee[em_number]
print("删除员工编号为" + em_number + "的员工成功")
#main方法
def main():
show_menu()
while True:
user_operate = input("请输入您的操作：")
if user_operate == '1':
add()
elif user_operate == '2':
delete()
elif user_operate == '3':
edit()
elif user_operate == '4':
show_all_info()
elif user_operate == '5':
show_single_info()
elif user_operate == '6':
print("欢迎下次登录员工管理系统！！")
break
else:
print("您的操作有误，请重新操作!")
main()
