3,006 Pointscan someone explain the for loop in the video
for key,value in kwargs.items(): setattr(self, key, value)
I read the teacher notes and under what the setattr function does but I want an understanding of the words used in the for loop.
Kenneth never mentioned kwargs.item before. nor did he specify an "Item" method. Is the "item" method a keyword used to denote the different attributes in the object?
Additionally, if I want to use this for loop in the future, do i have to use the exact words ' for key,value in kwargs.items():'? can the 'key' and 'value' argument only be used in this loop?

The names you give to the loop variables is entirely your choice, but "key" and "value" are good choices for names in this case because they refer to what kind of thing each one will hold.
