文本如下

Storage 1:
total storage = 204699 MB
free storage = 195091 MB
Storage 2:
total storage = 204699 MB
free storage = 200661 MB

如何实现最终结果为

Storage_1_total_storage = 204699 MB
Storage_1_free_storage = 195091 MB
Storage_2_total_storage = 204699 MB
Storage_2_free_storage = 200661 MB

笨方法：根据换行 split 后。遍历。再根据特定的条件，去拼接。。、

cinfigparser 模块吧这个明显符合 windows 配资文件的格式然后直接解析成字典

如果 Storage total storage 这些都是固定的话，用正则可以这么写：
`Storage (\d+):\ntotal storage = (.+)\nfree storage = (.+)`

如果不固定的话还是别用正则了，逐行遍历可能没那么麻烦。

for line in file:
if line[-1:] == ':':
prefix = line[:-1].replace(' ', '_')
else:
print (prefix+'_'+line.replace(' ', '_', 1))

for line in text :
if line.startswith('Storage') :
s = line.strip().replace( ' ', '_' )［:-1 ］
else :
k,v = line.split('=')
k = k.strip().replace( ' ', '_' )
line = '%s_%s = %s' % ( s, k, v )
out.write(line)
差不多就这样

```python3
for line in open("new.txt", "r"):
line = line.rstrip()
if line.startswith("Storage "):
storage = line.rstrip(':')
else:
key, val = map(lambda x:x.strip(), line.split('='))
new_key = f"{storage}_{key}".replace(' ', '_')
print(f"{new_key} = {val}")
```

6 楼的思路不错啊。学到了。replace 竟然有第三个参数。以前一直不知道
