這是做什麼用的？ - （「-h」，「--help」）中的ArgName [在Python中]

Question

有人能夠解釋這是什麼意思？請使用簡單的條款，街頭隨機的人可以理解。謝謝

嘗試在您的控制檯中測試這些東西...他們是不言自明的。

# set a value for ArgName 
>>> ArgName = "-h" 
# see if that value is in this tuple 
>>> ArgName in ("-h","--help") 
True # because ArgName = '-h' which is in the tuple 
>>> ArgName = "--help" 
>>> ArgName in ("-h","--help") 
True # because ArgName = '--help' which is in the tuple 
>>> ArgName = "something" 
>>> ArgName in ("-h","--help") 
False # because ArgName = 'something' which is NOT in the tuple
