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...

Do something with the <class 'set'> 6.集合推导式 集合推导式的用法与上述列表解析式的用法类似。不同之处在于集合推导式用的是花括号而不是方括号。并且,通过定义set 数据类型,可以删除重复的元素。7.字典生成式 除了列表解析式和集合推导式外,解析式特征还可用于字典数据类型的创建。dict由键值对组成,...

So when you do some_dict[5] = "Python", Python finds the existing item with equivalent key 5.0 -> "Ruby", overwrites its value in place, and leaves the original key alone. >>> some_dict {5.0: 'Ruby'} >>> some_dict[5] = "Python" >>> some_dict {5.0: 'Python'} So how ...
