函数定义和简单调用

公司新来部分新员工，定义函数并循环打印欢迎新员工的消息

employees = {"Chris": "NOC", "David": "PJM", "Brain": "SA", "John": "UX"}


def introduce_employee(employee, post):
    print("Welcome our new colleague " + username + ", his post is " + job + " !")


for key, value in employees.items():
    username = key
    job = value
    introduce_employee(username, job)

输出

Welcome our new colleague Chris, his post is NOC !
Welcome our new colleague David, his post is PJM !
Welcome our new colleague Brain, his post is SA !
Welcome our new colleague John, his post is UX !

 函数使用默认值

print_employees("Brain")
print_employees("John")
