I like the idea, but that's a fairly big
semantic change. What about
adding an -e option that takes an expression, and prints its value?
So you'd have
python -e "12 / 4.1"
(AFAICT, -e is unused at present).
That would be great. I did worry that changing the output would be backwards incompatible with code that shells out to Python using "-c", so a different command line option would be great. So long as it works with multiple statements (semi-colon separated) like the current "-c" behaviour.
Hey, what about this little module:
import sys for x in sys.argv[1:]: exec compile(x, '<cmdline>', 'single')
Then:
$ python -me '1+1; 2+2' 2 4
So now you can pip install e and then python
-me...
As an added bonus if the first argument is a module name it will print out the location of the module on the filesystem.
