Python: Using ConfigObj to create a .py file

Question

I am trying to use ConfigObj to create a python .py file.

The issues I'm facing are as follows -

1. How can I append the starting arguments(classname, init statements), import statements etc using configObj?
2. In ConfigObj, we can use section separators. How can I use comments as section names? Obviously, any incorrect code in the .py file and it'll not run. So, I want to separate things using comments as section headers.

The following is the code for the configspec file that I'm trying to use - (yes, I'm working on OpenFlow) -

from mininet.topo import Topo, Node

class MyTopo( Topo ):
    "Simple topology example."

    def __init__( self, enable_all = True ):
        "Create custom topo."

        # Add default members to class.
        super( MyTopo, self ).__init__()


        [["Define_Nodes"]]
        [[__many__]]

        [["Add_nodes"]]
    [[__many__]]

    [["Add_edges"]]
    [[__many__]]

    # Consider all switches and hosts 'on'
    self.enable_all()

topos = { 'mytopo': ( lambda: MyTopo() ) }

Finally, when I ran this spec, my code returns the following error -

in _handle_configspec
raise ConfigspecError('Parsing configspec failed: %s' % e)
ConfigspecError: Parsing configspec failed: Invalid line at line "1".       

Obviously, this means that I'm not able to create the right kind of configspec to run with ConfigObj.

Any answers to my 2 point Questions will be great!
