By far the easiest way to do it is to make a call to FMEDialog().sourcePrompt() (http://docs.safe.com/fme/html/FME_Objects_Python_API/fmeobjects.FMEDialog-class.html#sourcePrompt) and print out the results after having specified the sheet name in the dialog box. You can then copy/paste the relevant portions of the result into your production code.
Example:
import fmeobjects
def FeatureProcessor(feature):
print "-"*72
print fmeobjects.FMEDialog().sourcePrompt('', '')
print "-"*72
