Need to upgrade to use Python3

[genterminl]

Running from git head:

jack $./lsdrv 
  File "./lsdrv", line 323
    os.mkdir('/dev/block', 0755)
                              ^
SyntaxError: invalid token

It seems this is due to Python 3 (3.6.5 in my case) where octals apparently need to be specified Oo0755. However, changing that line leads to other errors (missing parens for print is the next one) and explicitly running with Python2 it works fine.
I'm not a Python programmer, so I don't know how much effort this requires, or if there is simply a way to explicitly request Python2 in the meantime.

@pturmel - Just wondering if you got anywhere with this?

I've used the script over the years to check my strages on Proxmox - but it no longer ships with Python 2.7 at all...

By changing the print statements to print(xxxx) - and then the permissions to 0oXXX - I've got to this point, and now I don't know what to do here:

Traceback (most recent call last):
  File "/root/bin/./lsdrv", line 423, in <module>
    probe_block('/sys/block/'+x)
  File "/root/bin/./lsdrv", line 342, in probe_block
    blk.__dict__.update(extractvars(runx(['blkid', '-p', '-o', 'udev', '/dev/block/'+blk.dev])))
                        ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
  File "/root/bin/./lsdrv", line 165, in extractvars
    for mo in varsre.finditer(buffer):
              ^^^^^^^^^^^^^^^^^^^^^^^
TypeError: cannot use a string pattern on a bytes-like object

It looks to me like the last commit to the code was over five years ago, so I have to wonder if this is now abandonware?

[pturmel]

Well, I'm still alive, but yes, low priority for quite some time now. Every time I look, I realize it needs substantial work to make it async-friendly in addition to the byte/string distinctions needed.

I've just opened a PR with code changes that make the script work both in python 2 and 3.
