This looks like you may not have installed the necessary dbus support
(e.g., src/org.neard.conf).  After building neard, you can install this
with:

$ sudo make install

If that isn't it, I'll need more info about your environment because I
don't get those errors.  To make sure we're on the same page, these steps
should get you going (this example on an amd64 running Ubuntu 20.04):

$ ./bootstrap-configure
$ make
$ sudo make install

<now insert your nfc hardware (a pn533 in this case)>

$ test/test-adapter list  # no need for sudo
 [ /org/neard/nfc0 ]
    Protocols = [ Felica MIFARE Jewel ISO-DEP NFC-DEP ]
    Mode = Idle
    Polling = false
    Powered = false
$ test/test-adapter powered nfc0 on
$ test/test-adapter list
 [ /org/neard/nfc0 ]
    Protocols = [ Felica MIFARE Jewel ISO-DEP NFC-DEP ]
    Mode = Idle
    Polling = false
    Powered = true
$ test/test-adapter poll nfc0 on Initiator
$ test/test-adapter list
 [ /org/neard/nfc0 ]
    Protocols = [ Felica MIFARE Jewel ISO-DEP NFC-DEP ]
    Mode = Idle
    Polling = true
    Powered = true

<now more a tag within range>

$ test/test-adapter list
 [ /org/neard/nfc0 ]
    Protocols = [ Felica MIFARE Jewel ISO-DEP NFC-DEP ]
    Mode = Initiator
    Polling = false
    Powered = true
$ test/test-tag list
 [ /org/neard/nfc0/tag0 ]
    Protocol = MIFARE
    ReadOnly = false
    Type = Type 2
    Adapter = /org/neard/nfc0
$ test/test-tag write /org/neard/nfc0/tag0 Text UTF-8 en-US "Hello World"
$ test/test-tag dump
[ /org/neard/nfc0/tag0 ]
  [ /org/neard/nfc0/tag0/record1 ]
      Representation = Hello World
      Type = Text
      Language = en-US
      Encoding = UTF-8

Not a py3-specific issue but I will fix this and other formatting issues.

Will fix all of these.

Looks like an artifact of tabs vs. spaces.  I'll fix that and other
formatting issues.

Thanks for the review.
