Hi Danny,

My program will be creating classes dynamically and I wish to save those
class definitions into the file and retrive these definitions at some
other point in time. I first thought of a simple strategy of storing the
class definition in file as a string and later executing the string so
that the class is created. But the class gets created inside the function
in which i call exec and its scope is confined to that function, so I
thought of using import instead of executing the string.

Can u suggest any other strategy for my problem.

Thank you,
Venkatesh
