Hi, thanks for the suggestions. this is my problem:
I have a metadata file that another user defines, and I don't know their structure in advance. They might have 300+ structures. the metadata defines the name and the tuple-like structure when read by python. my program reads in the metadata file and then generates python tuples corresponding to their structures. so they might provide a list of names, like 'bob','john','pete', with 3 structures per name, such as 'apple','orange','red' and I need 9 tuples in my code to store their data: bob_apple=() bob_orange=() .. pete_red=() I then populate the 9 tuples with data they provide in a separate file, and the filled tuples are then validated against the metadata to make sure they are isomorphic. Is this clear? thanks -- http://mail.python.org/mailman/listinfo/python-list
