Python2 will not be maintained upstream past 2020, so a lack of python3
bindings certainly feels like a non-starter.  As for why the kernel team
decided to drop the python build-dep in 13.04, I'm not sure, and it's a
conversation worth having.

  After installing libpython, downloaded ubuntu 17.04 linux source code and 
compiled perf tool then it works fine.

  # ./perf script  -g python 
  generated Python script: perf-script.py

  but when I run perf tool without rebuilding after installing libpython
  it shows an error

  # perf script  -g python 
  Python scripting not supported.  Install libpython and rebuild perf to enable 
it.
  For example:
    # apt-get install python-dev (ubuntu)
    # yum install python-devel (Fedora)
    etc.
  root@p8wookie:/home/Mamatha/ubuntu/ubuntu-zesty/tools/perf# perf --version
