How to read ansic file into a pre-defined class?

I have a series of files written in the following format,

2         # number of classes
100       # number of items for the first class object
0   foo
1   foo
...
99  foo
150       # number of items for the second class object
0   bar
1   bar
...
149 bar

ultimately I want to read the file to two *structs* (sorry for my C 
jargon,
just started playing with Python), with attributes number_of_items and
data_array.

I wrote a simply code to read and split each line into a list, then try 
to 
tell the meaning of each line by the number of elements of each line list 
and
the its position in the file. But it is definitely not the way Python 
should
be used.

Any ideas on how to implement a more elegant yet efficient python version?

Thanks.
