combining more than two features

[arashtayyebi]

Hi all,
I have some important features like as ( '[O]', 'CN(C)(C)C', ' CH(-[O])-[O]', 'c(:[c])-[OH]', 'c(:[c])-[S]', ' CH2-[NH]') and I want to combine them and make a new SMILES.
Is there any way to see all the possibilities to integrate these fragments?

@arashtayyebi can you provide more information about what you mean by integrating or combining fragments?

@greglandrum The idea is like as combining two molecules
mol1 = Chem.MolFromSmiles('NH-C=[O]',sanitize=False)
mol2 = Chem.MolFromSmiles('CH2-[CH2]')
if I try :
combo1 = Chem.CombineMols(mol1,mol2)
it works,
but if I have more than two molecules, how can I combine them like as combo1?
for instance, if I input mol3:
mol3 = Chem.MolFromSmiles('[O]=[CH]')
so the following code will not work
combo2 = Chem.CombineMols(mol1,mol2,mol3)
