A test is missing. ;) Is there an example how to test this? At the very least I guess we should just try to generate the code, to make sure the Python code runs. > > If anyone wants to slack off for a few minutes and make a little > contribution this one is perfect. > > What are the SymPy functions that should be supported?

Since very library might have a different syntax / argument order, I am not sure how to handle those. We can maybe provide a dictionary to the user so that he can specify his preferred names for special functions?
