+# 字段的基本信息
+## 1. 字典是Python中唯一的映射类型
+## 2. 字典是无序的
+## 3. 字典是可迭代对象
+## 4. 字典的构成
+	键：key
+	值：value
+	映射：键映射值
+	键-值：键值对，又叫项 
+# 字典的操作
+## 1. 添加、更新键值对 
+## 2、访问字典  get()按键访问值
+## 3、浅拷贝 copy()
+## 3. 删除键值对 del删除键值对 pop() popitem() clear()清空字典
+## 4. 判断键是否存在字典里面 in
+## 5. len属性
+## 6. keys
+## 7. values
+## 8. items
