[python] restart self within it

import os, sys

os.execv(sys.executable, ['python'] + sys.argv)

# sys.executable: the python path you are using which will auto know if you are using virtualenv    
#                 e.g: /home/pd/.virtualenvs/competehunt_main/bin/python'  [so if it not what you want, write it manually]

# of course, sys.argv is the current file name if you donnot add extra params [yes, add it if need to]
# so ['python'] + sys.argv  ==>   ["python", "current.py"]
