Save / load workspace

Save your lab results on this server for 48 hours. Use the token to continue on another device. Anyone who knows the token can open your workspace.

Save workspace

A name is required when you first save and is then permanently bound to this workspace. Task values, entries and progress are saved together.

Load workspace

New workspace

Start with empty results and a name of your choice. Previously saved tokens remain valid until they expire. Unsaved changes in this tab will be discarded.

Saving also transfers any included measurement files and analysis videos to this server. Running simulations are saved as a set of results and displayed in a paused state when loaded.

Inheritance

Back to the lab Theoretical foundations

Three exercises on the base class Messreihe, which is already in the editor. Part 2 copies the code from part 1 with a button.

Part 1 — TemperaturVersuch inherits from Messreihe

Own attribute with super(), a new method.

Exercise

The finished base class Messreiheis already in the editor. Derive the class TemperaturVersuch from it. Its constructor additionally receives einheit="°C" and stores it in the attribute einheit; it takes over name and readings with super().__init__(name, messwerte). The method max_temp() returns the highest temperature.

Example TemperaturVersuch("Erwärmung", [20, 24, 22]).max_temp() yields 24.

Part 2 — Own __str__ for the temperature experiment

    
Overriding an inherited method.

    
Exercise
Copy your class from part 1 and, in TemperaturVersuch , override the method __str__(), so that the experiment states maximum and unit instead of the mean.
Example print(TemperaturVersuch("Erwärmung", [20, 24, 22])) shows exactly Temperaturversuch Erwärmung: 3 Werte, Maximum 24 °C. An ordinary Messreihe still introduces itself as before.

Part 3 — Pressure series with limits

    
A second subclass for the lab.

    
Exercise
Derive from Messreihe the class Druckmessreihe(name, messwerte, minimum, maximum) and store the limits in the attributes minimum and maximum. The method alle_plausibel() gibt True if every reading lies between the limits, limits included. ausreisser() returns the list of readings that lie outside.
Example For the values [2.0, 11.5, 2.4] with the limits 0 and 10, alle_plausibel() equals False and ausreisser() equals [11.5].
