Queue - FIFO (First In First Out): A queue is something where the first item that comes into the queue is also the first item get out of the Queue. Stack - LIFO (Last In First Out): In stack the element pushed in last get popped out first. Let's see some more examples inlist:...
8.2.5 Is Something in a List?# 判断一个元素是否在一个list里,可以使用"in"或"not in",而python则会返回一个逻辑布尔值。而这项操作并不会改变list本身。 Copy >>>some = [1,9,21,10,16]>>>9insomeTrue>>>15insomeFalse>>>20notinsomeTrue 8.2.6 Lists are in Order# 使用"sort"可以对list...
