Question

I wrote a program to read a registry entry from a file.
And the entry looks like this:

reg='HKEY_LOCAL_MACHINE\SOFTWARE\TT\Tools\SYS\exePath' #it means rootKey=HKEY_LOCAL_MACHINE, subKey='SOFTWARE\TT\Tools\SYS', property=exePath

I want to read this entry from the file and break it into rootKey, subKey and property.
Apparently, I can do it this way:

rootKey = reg.split('\\', 1)[0]
subKey = reg.split('\\', 1)[1].rsplit('\\', 1)[0]  #might be a stupid way
property = reg.rsplit('\\, 1)[1]

Maybe the entry is a stupid one, but any better way to break it into parts like above?

Answer 1

import re

t=re.search(r"(.+?)\\(.+)\\(.+)", reg)
t.groups()
('HKEY_LOCAL_MACHINE', 'SOFTWARE\\TT\\Tools\\SYS', 'exePath')
