A shop keeps stock = {"apples": 12, "bananas": 7}.
Contributed by StemPy LabTry it on paper first. A hint, the key idea and the worked solution are here when you need them.
A shop keeps stock = {"apples": 12, "bananas": 7}. Show the number of apples, and the number of mangoes, which are not in the dictionary, without an error.
Need a reminder? The key ideaShow
get(key, default) never gives a KeyError.
The worked solution
Have you tried it?
Work it out on paper first. It is fine to get stuck or make a mistake: that is how we learn. When you are ready, compare your working with the solution.
stock["mangoes"] would stop with a KeyError. We use get with a default of 0:
stock.get("apples", 0)gives12.stock.get("mangoes", 0)gives0, because there is no such key.
