小编DC0*_*C00的帖子

我正在尝试在OCaml中创建一个字典,将字符串映射到字符串列表.我已经引用了本教程的基本字符串到字符串映射,但我需要一些帮助制作列表.

这是我想用Python做的事情:

>>> food = {}
>>> food["fruit"] = ("blueberry", "strawberry", "kiwi")
>>> food["veggie"] = ("broccoli", "kale")
>>> for k in food:
...     for v in food[k]:
...         print k, "-->",v
...
fruit --> blueberry
fruit --> strawberry
fruit --> kiwi
veggie --> broccoli
veggie --> kale

提前致谢
