python实现判断数组是否包含指定元素的方法

python判断数组是否包含指定的元素的方法，直接使用in即可，python真是简单易懂

print 3 in [1, 2, 3] # membership (1 means true
inventory = ["sword", "armor", "shield", "healing potion"]
if "healing potion" in inventory:
  print "You will live to fight another day."

运行结果如下：

True
You will live to fight another day.
