How can I execute a statement followed by a value in a single line?

The grammar or Python is deliberately designed so that the body of a
lambda expression cannot contain any statements. So your original code,
where you defined a separate `count_in' procedure, is probably what you
want.
Although using `reduce' is kind of silly in this case because you aren't
computing a new dictionary every time, but instead you are mutating the
_same_ dictionary every time. Your original code that used a `for' loop
is actually much clearer.
