Go over the notes from last class. Note, to run the code for the record-jar parser you will need to download the source file that is linked and save it to your current working directory.

Self Study

1. Write a yaml2json program in Python that reads an input file in yaml format and writes out a file in json format.
2. Write a rjar2yaml program in Python that reads input in record-jar format and converts the information to yaml format on standard output.
3. The yaml file produced by rjar2yaml will probably not be identical to the yaml file we wrote by hand to describe the same data. Both are valid yaml files, why are they different?
