Back on new functions for motif quorums. We jump function 7 in order to
explain “simpler” ones, 8 and 9. Both functions use
already seen here
generators, which are functions that use the
statement to generate iterators. The generator is very similar to a
function but instead of returning a value, it yields one and waits for
another call to resume. In function 8, a generator is used to return the
motif sequence that is used as a key in the
defaultdict. Notice the
scope of the generator that is coded inside a function.

In function 9 a
very similar structure is used but in this cases instead of a “pure”
generator it uses
generator expressions which a very similar to
but with parentheses instead of square brackets.
are generators that can be written in one line and have identical
behaviour as generators coded in the “regular” inception. In the
function below the
generator expressions provide the iterator for the
motif as index. Very simple and elegant.

In the next post we will go back to the statistical module and soon we will see the remainder 5 functions sent by Mike.
