Computational Complexity
摘要
InComputational complexity the lastComplexity chapter we developed a drawing program. To hold the drawing commands we built the PyList container class which is a lot like the built-in Python list class, but helps illustrate our first data structure. When we added a drawing command to the sequence we called the append method. It turns out that this method is called a lot. In fact, the flower picture in the first chapter took around 700 commands to draw.
