correct example (#276)

map() is a function in python2, and iterator in python3+;

In any case - map is inefficient compared to either comprehensions (most efficient), or simple loops (close second).
SInce in this case, data.append() returns nothing, use a simple look.
It is clearer, more efficient, and works with both python2 and python3
