Just use pickle. From the docs:

| The marshal module exists mainly to support reading and writing

| Therefore, the Python maintainers reserve the right to modify the
| marshal format in backward incompatible ways should the need
| arise. If you're serializing and de-serializing Python objects,
| use the pickle module instead.
