if the modules behave nicely, and don't do silly stuff when first imported,
something like
try:
import mymodule
except ImportError:
install_module("mymodule")
import mymodule # retry
usually works.
if you have lots of modules, you can use something like
MODULES = "mymodule", "myothermodule", "sys"
for module in MODULES:
try:
__import__(module)
except ImportError:
install_module(module)
...
import mymodule # will fail if installation failed
import myothermodule, sys
....
