python - 如何处理python类中两个参数中的多个值

Question

我想创建一个像这样的Python类:

类.py

class MyClass(object):
    def __init__(self, email, delay_time=0):
        print email
        print delay_time
if __name__ == "__main__":
    a = MyClass()

email 参数是强制性的，并且应该能够包含多个值，delay_time 应该是一个可选参数。我想这样调用它:

python class.py abc@email.com abc1@email.com abc2@email.com 3600
python class.py abc@email.com abc1@email.com

我已经用 docopt 尝试过这个，但也没有运气。请提出建议。

尝试这个脚本

import sys
class MyClass(object):
    def __init__(self, emails, delay_time=0):
        for email in emails:
            print email
        print delay_time
if __name__ == "__main__":
    if len(sys.argv)>1:
        emails = sys.argv[1:-1]
        delay = sys.argv[-1]
        try:
            delay = int(delay)
        except ValueError:
            emails.append(delay) #there's no delay
            delay=0
        a = MyClass(emails,delay_time=delay)

这是输出

$:~/dev/stack$ python class.py abc@email.com abc1@email.com abc2@email.com 3600
abc@email.com
abc1@email.com
abc2@email.com
3600
$:~/dev/stack$ python class.py abc@email.com abc1@email.com
abc@email.com
abc1@email.com
