Migrate script from Python2 to Python3

[eribertomota]

Made with a little help of 2to3 script. This patch is from Debian.

[samueltardieu]

The script is already compatible with Python 3. The two main parts of this patch are useless:

• There is no need to have two pairs or parentheses around print() argument.
• There is no need to build an intermediate list from an iterator just to iterate over the list.

If this patch is really in Debian, you should consider telling them to remove it, they can keep the first line if their Python is still Python 2 by default (Python 3 has been released for 11 years already…).

No problem to use your original script in Debian. I only need to change the first line to python3. However, I did some tests and this script seems not work.
