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.

Methods and Objects in Action

Back to the lab Theoretical foundations

Four exercises: first a measurement series that calculates and introduces itself, then the dice simulation and a pressure sensor. Part 2 copies the code from part 1 with a button.

Part 1 — The class Messreihe

A list as an attribute and a method that calculates.

Exercise

Write the class Messreihe. The constructor receives name and messwerte and stores both in the attributes name and messwerte — the readings as its own list. The method mittelwert() returns the mean of the readings.

Example Messreihe("Druck", [1, 2, 3]).mittelwert() yields 2.0.

Part 2 — The measurement series introduces itself

    
__str__ for readable output.

    
Exercise
Copy your class from part 1 and add the method __str__(). It returns a text that states the name, the number of values and the mean.
Example print(Messreihe("Druck", [1, 2, 3])) shows exactly Messreihe Druck: 3 Werte, Mittelwert 2.0.

Part 3 — Simulating a pair of dice

    
Objects in a loop, running mean.

    
Exercise
The finished dice class from the experiment “Classes and Objects” is already in the editor. Below it, write the function simuliere_wuerfelpaar(anzahl, seed=0): it first calls numpy.random.seed(seed) , builds a four-sided and a six-sided dice and in every pass rolls the four-sided one first, then the six-sided one. It returns a list that, after each pass, contains the mean of all sums so far.
Example The first entry is the first sum; the second entry is the mean of the first two sums. For anzahl = 0 the list is empty.

Part 4 — A pressure sensor that checks readings

    
A method that decides.

    
Exercise
Write the class Drucksensor(name, minimum, maximum, einheit="bar") and store all four values as attributes. The method ist_plausibel(wert) gibt True if the value lies between minimum and maximum, limits included. spanne() returns the difference between maximum and minimum, and __str__() introduces the sensor.
Example print(Drucksensor("P1", 0, 10)) shows Drucksensor P1: 0 bis 10 bar.
