+
+对于 Lambda 函数，KCL 可以自动推断函数体中的返回值类型，尽管我们也可以明确指定它。下面是一个 KCL 代码示例：
+
+```python
+f1 = lambda t: Type1 {
+    Type2 {}
+} # f1 的类型是 (Type1) -> Type2
+f2 = lambda t: Type1 -> Type2 {
+    Type2 {}

+## 60. 在 KCL 中如何将列表的列表转换为单个列表？
+
+要将列表的列表转换为单个列表，我们可以使用 sum() 函数。例如，如果我们有多个列表，比如 `[[1,2],[3,4],[5,6]]`，我们可以使用以下 KCL 代码将这三个列表转换为单个列表：
+
+```python
+final_list = sum([[1,2],[3,4],[5,6]], [])
+```
