Python中的insert函数用于将一个元素添加到列表的指定位置中。其用法如下:
```python
list.insert(index, new_item)
```
其中,index表示新元素应该插入的位置,new_item表示要添加的新元素。例如:
```python
fruits = ['苹果', '西瓜', '水蜜桃']
fruits.insert(1, '水晶梨')
print(fruits)
```
输出结果为:
```python
['苹果', '水晶梨', '西瓜', '水蜜桃']
```
与append函数相比,insert函数可以将元素添加到任意位置,而不仅仅是列表的结尾。如果传入的位置在列表中不存在,新元素将被添加到列表的结尾。字符串、元组和列表的位置都是从0开始计算的。<span class="em">1</span><span class="em">2</span>
