# To help render markdown
from IPython.core.display import display, HTML
from markdown import markdown
def render_markdown_raw(m): return display(HTML(markdown(m))) # must be last element of cell.
def render_markdown(m): return render_markdown_raw(m.toMD())

# import the relational algbera operators
from relation_algebra import Select, Project, Union, NJoin, CrossProduct, BaseRelation
from relation_algebra import get_result, compare_results
