The notes are later merged into our repository.* # Discussion ## Data Structures & Structuring Data ### Properties and Use Cases for Python's Default Data Structures #### dict Properties: - Mapping: key (hashable, unique, immutable) -> value - Mutable Use Cases: - eh klar #### list Properties: - Sammlung von Werten - Ordnung - Mutable - Homogen (in Erwartung) Use Cases: - eh klar #### tuple Properties: - fühlt sich kleiner an - immutable - Ordnung - heterogen Use Cases: - eh klar #### set Properties: - Menge im mathematischen Sinn - mutable - Werte müssen hashable sein Use Cases: - eh klar ### Properties and Use Cases for Scientific Python's Major Data Structures #### Name of Data Structure Properties: - ... Use Cases: - ... ### Serialization Formats #### Name of Format Propteries: - ... Use Cases: - ... ## Code Quality ### What is code quality? Or: What is good code? Einfach verständlich | Sinnhaftigkeit: - Was soll mein Code können? - Wie kann ich mich breit aufstellen? - YAGNI : you ain't gonna need it ? Code kann sich mit neuen Anforderungen weiter entwickeln (Aktuelle Bibliotheken verwenden) Gut dokumentiert, d.h. zumindest || - README - Docstrings Gut getestet | - Hohe Code coverage Im Betrieb - Monitoring (Logging) Sinnvolle Struktur im Hinblick auf Funktionen und Klassen | - bspw. entlang Front End und Back End - Schnittstellen - Domäne - Kappselung von Funktionalität (was gehört zusammen und was nicht) Performance (Ausführungsgeschwindigkeit, Speicherbedarf, numerische Effizienz) || Coding Guidelines (Standards) | - Projekt - Domäne - Sprache (PEP8) #### Kent Becks Four Rules * Passes the tests * Reveals intention * No duplication * Fewest elements TBD for later: fewest elements? ### Why does it matter? - **Dauerhafte Nutzung ermöglichen** - Kann ich Projekt erweitern? - Zugänglich - Seelenfrieden, Freude an der Arbeit Verschiedene Perspektiven... ### How do you achieve *good* quality? Definieren was gut heißt? Gemeinsames Commitment (Hängt das von der Technologie ab?) Regelmäßig überprüfen ob man den eigenen Standards gerecht wird Zeit nehmen um Verbesserungen durchzführen ## Code review ### What do we hope from a review? Verena hätte gerne: 1. Macht der Code was er soll? --> Wie kann man das verifizieren? Bei wem liegt die Verantwortung? Wie designe ich Test Cases? 2. Erfüllt der Code unsere Ansprüche? Wie kann ich es besser machen? --> Konkret Schnelle Rückmeldung Organisatorisch Wertschätzung ### What is important to **you**? ### How do we perform a review?
