cmdline args to a piped python prog

[leo]

hi there

a python file can evaluate cmdline arguments like

python myprog.py arg1 arg2 arg3...

when i feed python with my program via terminal input like

cat myprog.py | python

how can i then specifiy the cmdline arguments arg1 arg2 arg3...?

thanks a lot, leo

ps: wondering why i ask? -- emacs calls python code from abuffer always in
the latter way.

You could say cat myprog.py | python - arg1 arg2 arg3
Then sys.argv[1:] contains the arguments.

By the way cat myprog.py | python * is equivalent to python * < myprog.py
No need for cat.
