A yield expression is used when defining a generator function. [S1]
Yield
yield expression is used when defining a generator function. [S1]
Classes vs generators
Classes provide a means of bundling data and functionality together. [S2]
Each class instance can have attributes attached to it for maintaining its state. [S2]
