Multiple ways, yes.

Spawning a ros node is no different from just running a process. So
the standard Python subprocess module will work.

If you want to get fancier, there are two Python APIs for running
roslaunch within your own process:

 * roslaunch.scriptapi [1]
 * roslaunch_caller (unsupported)
