• dna_sequencer.py

Task 8: Upgrade

We now equip our laboratory with a new DNA sequencer. The DNA Master 3000 has a few new gimmicks:

• It produces sequences with a length of 3000.
• When analyzing, it
  1. Prints the model and serial number (like the 2000-variant)
  2. Prints the sample it is processing
  3. Does the analysis
  4. Outputs a preview with the first 20 bases of the sequence it produced (only if the analysis added a DNA sequence to the sample)
• This new model has a functionality run_demonstration(…) which acts as if analyzing a sample, but does not actually modify the sample and uses the fixed sequence ACGT repeated 5 times.
• Unlike the 2000 model it does not always arrive in a clean state

Create a new (sub-) class for this device. From which class should you inherit, if any? Which methods do need to be overridden?
