Is the 'print (x),' [trailing comma] syntax valid for function syntax? Print "x", in Py2 means suppress the trailing newline. You need to actually run the scripts (old, new PYTHON=python2, new PYTHON=python3) and compare the output. This: print "%-40s %10s\n" % ("comm [pid]/syscalls", "count"), can be reworked as: print ("%-40s %10s" % ("comm [pid]/syscalls", "count")) See: https://build.opensuse.org/package/view_file/devel:tools/perf/port-failed-syscalls-by-pid-script-to-python3.patch?expand=1
