Yet one more offering: en.wikipedia.org/wiki/Python_Pipelines
This is my project - and a way you could help is:
I'd give you the specification of a "stage" and you'd develop a python
function or class that would implement that stage. The first stages
would be fairly simple, then things would get more involved.
I'd give you a testing framework in which to test a stage.
So the task would look like:
Specification of stage "foo": print the length of the input and if the
length is less that 10 send the input to the output.
The simplest solution you could code is:
def run(input, output, spec=None):
print len(input) # input is a character string of arbitrary length
if len(input) < 10:
output(input) # output is a function that sends its argument to
"the output".
Then you'd test it thusly:
import pipetest
pipetest.test("Short")
pipetest.test("Longer than 10")
Running the above should display:
5
Short
14
Is that clear? Is that interesting? There are a lot of stages to be
developed; many of them are much more complex, so this could provide for
a step-by-step evolution of your skills.
Let me know one way or the other or ask clarifying questions.
