common-lisp LOOP, a Common Lisp macro for iteration Looping over Hash Tables
Example
(defvar *ht* (make-hash-table))
(loop for (sym num) on
'(one 1 two 2 three 3 four 4 five 5 six 6 seven 7 eight 8 nine 9 ten 10)
by #'cddr
do (setf (gethash sym *ht*) num))
(loop for k being each hash-key of *ht*
do (print k)) ; iterate over the keys
(loop for k being the hash-keys in *ht* using (hash-value v)
do (format t "~a=>~a~%" k v))
(loop for v being the hash-value in *ht*
do (print v))
(loop for v being each hash-values of *ht* using (hash-key k)
do (format t "~a=>~a~%" k v))
