在Python中,没有直接的"for each"循环,但可以使用"for in"循环来达到相同的效果。"for in"循环用于遍历可迭代对象,如列表、字符串、元组、集合和字典。下面是一个示例代码来演示"for in"循环的用法:
```
nums = [1, 2, 3, 4, 5]
for num in nums:
print(num)
```
这段代码将会遍历列表`nums`中的每个元素,并将其打印出来。输出结果将是:
```
1
2
3
4
5
```
注意,`num`是一个临时变量,用于存储每次迭代的值。在循环体内,你可以对`num`进行任何操作,根据你的需要进行处理。希望这个例子能够帮助你理解"for in"循环的用法。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
