Dictionaries can be created using thedictfunction. capitals = {} capitals["svk"] = "Bratislava" capitals["deu"] = "Berlin" capitals["dnk"] = "Copenhagen" In the third way an empty capitals dictionary is created. Three pairs are added to the dictionary. The keys are inside the square br...
Let’s look at a diagram to clarify this idea. 我们将建立一个简单的字典,其中有与value对象关联的第一个键。 We’re going to set up a simple dictionary where we have our first key that’s associated with a value object. 我们有第二把钥匙,和另一个物体在一起。 We have our second key th...
