1. 打印数字 0 到 9: ```python [print(i) for i in range(10)] ``` 2. 将列表中的所有元素平方: ```python lst = [1, 2, 3, 4, 5] squares = [i**2 for i in lst] ``` 3. 求列表中的最大值: ```python lst = [10, 20, 30, 25, 15] max_value = max(lst) ``` 4. 求列表中的偶数: ```python lst = [1, 2, 3, 4, 5] even_numbers = [i for i in lst if i % 2 == 0] ``` 5. 对字符串中的字符进行排序: ```python string = "hello world" sorted_str = ''.join(sorted(string)) ```
