PCEP 3.2 Collect and process data using tuples

  • tuples: indexing, slicing, building, immutability; tuples vs. lists: similarities and differences, lists inside tuples and tuples inside lists.

PCEP 3.3 Collect and process data using dictionaries

  • dictionaries: building, indexing, adding and removing keys; iterating through dictionaries and their keys and values, checking the existence of keys; keys(), items() and values() methods.
