What should I name these vars

[RickyWilson]

import os
import os.path
import sys
import readline


def modcmd(arg):
  # I want to declare the the sys.executable+" "+sys.prefix+"/bin/"
  # as a constant but don't know what to name it.
  os.system(sys.executable+" "+sys.prefix+"/bin/" +arg)

# I would also like to declare sys.prefix+"/bin/pip as a constant
# but again I'm not sure what to name it.
if not(os.path.exists(sys.prefix+"/bin/pip")):
  print("You need to install pip first.")
  
print("Input pip commands, ie: pip install {module}")
while(True):
  cmd=input("-->")
  if (cmd==""): break;
  modcmd(cmd)

Call it whatever it is.  bin_path, pip_path, etc.
