The use of 'from __future__' implies the minimum supported Python2 version is now v2.6 Signed-off-by: Tony Jones Cc: Paolo Bonzini Link: http://lkml.kernel.org/r/20190222230619.17887-12-tonyj@suse.de Signed-off-by: Seeteena Thoufeek Signed-off-by: Arnaldo Carvalho de Melo --- diff --git a/tools/perf/scripts/python/stackcollapse.py b/tools/perf/scripts/python/stackcollapse.py index 1697b5e18c96..5e703efaddcc 100755 --- a/tools/perf/scripts/python/stackcollapse.py +++ b/tools/perf/scripts/python/stackcollapse.py @@ -19,6 +19,8 @@ # Written by Paolo Bonzini # Based on Brendan Gregg's stackcollapse-perf.pl script. +from __future__ import print_function + import os import sys from collections import defaultdict @@ -120,7 +122,6 @@ def process_event(param_dict): lines[stack_string] = lines[stack_string] + 1 def trace_end(): - list = lines.keys() - list.sort() + list = sorted(lines) for stack in list: - print "%s %d" % (stack, lines[stack]) + print("%s %d" % (stack, lines[stack]))
