import os, subprocess
pyrcfile = file(os.getenv("HOME")+"/.pythonrc","w")
pyrcfile.write("""import rlcompleter
import readline
import os
readline.parse_and_bind ("bind ^I rl_complete")
def clear():
    os.system('clear')""")
pyrcfile.close()
try:
	bashrcfile = file(os.getenv("HOME")+"/.bash_profile", "a")
except:
	bashrcfile = file(os.getenv("HOME")+"/.bash_profile", "w")
bashrcfile.write("\nexport PYTHONSTARTUP=~/.pythonrc")
bashrcfile.close()
subprocess.call("source ~/.bash_profile",shell=True)
