I would like to know how to write python function which can flatten generator which yields another generators or iteables (which can also yield another generators/iterables ... possibly infinitely).
Here is example:
gen(gen(1,2,3), gen(4,5,6), [7,8,9], [gen(10,11,12), gen(13,14,15)])
note: gen - means generator object, content between parentheses after gen is data that will generator gen yield.
The expected result after "flattening":
gen(1,2,3,4,5,6,7,8,9,10,11,12,13,14,15)
It is necessary for the flatten function to return generator too! (because otherwise, the preceeding usage of generators would be meaningless).
Just to note, I am using python 3.
Thanks!
