Python-RPM show different result between Python 3 and Python 2

I am transfering a script from Python 2 to Python 3.

I am using the following code to check an RPM package.

import rpm
TS=rpm.TransactionSet()
CHECKPACKAGE=TS.dbMatch('name', 'gpm')
for h in CHECKPACKAGE:
    print("%s-%s-%s" % (h['name'], h['version'], h['release']))

if (h['version'] == "1.20.7") and (h['release'] == "7.60"):
   print("=> check gpm: version gpm is in sync")
   print("")
else:
   print("!!!check gpm: version gpm is NOT in sync please check!!!")
   print("")

With Python 2 I got

gpm-1.20.7-7.60
=> check gpm: version gpm is in sync

With Python 3 I got

b'gpm'-b'1.20.7'-b'7.60'
!!!check gpm: version gpm is NOT in sync please check!!!

What can I do to have the same result with Python3?

Regards

Call method decode() on h['release'] and h['version']:

if (h['version'].decode() == "1.20.7") and (h['release'].decode() == "7.60"):
...

It looks like you have a byte string instead of a string.

You can understand it comparing gpm-1.20.7-7.60 and b'gpm'-b'1.20.7'-b'7.60'.

decode() will remove b''.
