Python Programming

Download sequence.py. Examine the code.

• There are two classes: FibonacciSequence and TriangleNumberSequence. Try to understand what each class does.
• What does the term() method of each class return?
• How is the length attribute used in each class?
• The __iter__() and __next__() methods allow Python to treat these classes as iterable sequences.
• Look at the test code at the end of the script to get a feel of how both classes are used.

Run the code (python3 sequence.py). It should work and generate the correct sequences.
