Using switches with exec?

[=?iso-8859-1?q?Premshree=20Pillai?=]

Hello,

I need to run a Python program dynamically within
another program. I am using exec for the purpose. Is
there a way to pass parameter switches to exec?

You can pass a globals-dictionary to exec, which can hold the switches
values.

Could you please elucidate with a sample script.
Suppose I need to pass the switch "-w" to the
dynamically loaded code (using eval()/exec()).
Any help is appreciated.

Options aren't typically passed to "code". They're passed to the main
function of a program. For example:

def main(argv):
o = GameOptions()
o.parse(argv[1:])
...

If your code is structured like this, you can avoid using eval() and exec
altogether and simply import and call the main function:

from foo import main
main(['progname', '-w'])

Hope this helps,

Jp
