我想将其转换为：

NODE1.storePool_ByteLockAlloc=0;NODE1.storePool_ClientAlloc=60;NODE1.storePool_CopyStateAlloc=0;............NODEn.storePool_ByteLockAlloc=165;

对于我从输出中获得的所有节点（不仅是 3 个）。

我试过用这个替换输出：

output.replace(' ', '').replace('Alloc', 'Alloc=').replace('\r','').replace('\n',' ')

但这并没有给我我需要的结果。

一些想法？

非常感谢您的帮助。

如果您将输出捕获到一个长字符串中，您可以使用正则表达式来查找感兴趣的行并将它们解析为您请求的格式：

import re

output = """

Instance: nfs4_diag

Scope: NODE1

for match in re.findall(r'Scope: (NODE\d+)|(storePool_.*)', output):

    if current_node and metric:
        name, value = metric.strip().split()
        rv.append(f'{current_node.strip()}.{name}={value}')
