我是k3这个机器出了问题,但是没有任何理由,因为都是相同的配置,啥都是一模一样的,如果报错应该是都报错,所以我下面选择忽略
yum -y install kernel*
如果你感觉没问题的话可以直接忽略这个错误

`
join
()` 是 Python 中字符串的一个方法,它可以将一个可迭代对象中的所有元素拼接成一个字符串。
具体而言,`
join
()` 方法可以在一个字符串对象上调用,其语法为:
```python
new_string = separator.
join
(iterable)
其中,`separator` 是一个字符串,它将会插入到可迭代对象 `iterable` 中的元素之间,用于拼接成一个新的字符串 `new_string`。
举个例子,假设有一个列表:
```python
words = ['Hello', 'world', '!']
我们可以使用 `
join
()` 方法将其拼接成一个字符串:
```python
new_string = ' '.
join
(words)
print(new_string) # 输出:'Hello world !'
在这个例子中,我们使用空格字符串 `' '` 作为分隔符将列表 `words` 中的元素拼接成了一个新的字符串。
需要注意的是,`
join
()` 方法只能用于字符串之间的拼接,如果需要将数字或其他类型的数据拼接成字符串,需要先使用 `str()` 函数将其转换为字符串类型。
