Question

以下是生成问候语消息的简单脚本：

def greeting(event, person):
    print("Happy " + event + ", dear " + person + ".")

event = "Birthday"
person = "Emily"
greeting(event, person) # Happy Birtday, dear Emily.

event = "New Year"
person = "Mark"
greeting(event, person) # Happy New Year, dear Mark.

有没有办法获得相同的结果，但只调用greeting函数一次？

Answer 1

您可以将其置于循环中以处理名称和事件列表。我建议保持内部功能相同，并从外部发射一系列数据。根据您的应用，里程可能会有所不同。

def greeting(event, person):
    print("Happy " + event + ", dear " + person + ".")

event_list = [("Birthday", "Emily"),
              ("New Year", "Mark")]
for event, person in event_list:
    greeting(event, person)

Answer 2

如果你只想让函数循环输入，这应该可以工作：

def greeting(messages):
    for event, person in messages:
        print("Happy " + event + ", dear " + person + ".")

greeting([('Birthday', 'Emily'), ('New Year', 'Mark')])

Answer 3

如果您可以修改问候语：

Answer 4

其他用户提到的任何一个选项都可以使用。这取决于你是想把循环放在函数中还是放在函数之外：

def greeting(event, person):
    print("Happy " + event + ", dear " + person + ".")

for event, person in [("Birthday", "Emily"),
              ("New Year", "Mark")]:
    greeting(event, person)

调用配对参数的函数
