+abstract: >-
+  This lesson introduces the basics of profiling and
+  optimising Python code. The course is designed to be
+  accessible to Python users of all skill levels (beyond
+  total beginner). The optimisations presented should be
+  considered performance best practices, they are
+  demonstrated with small programming patterns that
+  demonstrate multiple approaches in code to achieve the
+  same result with differing performance.
