反轉元素

Created: November-22, 2018

元組內的反轉元素

colors = "red", "green", "blue"
rev = colors[::-1]
# rev: ("blue", "green", "red")
colors = rev
# colors: ("blue", "green", "red")

或者使用 reverse（反轉給出一個可轉換為元組的迭代）：

rev = tuple(reversed(colors))
# rev: ("blue", "green", "red")
colors = rev
# colors: ("blue", "green", "red")
