This commit does not make the script python 3 compatible, it is a
5d360b
preparation that fixes the easy and common incompatibilities.
5d360b
5d360b
Print is a function in python 3 and therefore needs braces around its
5d360b
arguments.
5d360b
5d360b
Range does not cast a gdb.Value object to int in python 3, we have to
5d360b
do it ourselves.
