The essence of functional programming comes from the ways we can easily combine generator expressions and generator functions to create very sophisticated composite processing sequences. When working with generator expressions, we can combine generators in several ways.
One common way to combine generator functions is when we create a composite function. We may have a generator that computes (f(x) for x in range()). If we want to compute g(f(x)), we have several ways to combine two generators.
We can tweak the original generator expression as follows:
g_f_x = (g(f(x)) for x in range())
While technically correct, this defeats any idea of reuse. Rather than reusing an expression, we rewrote it.
We can also substitute ...
