It would help to know how you plan to use it. I *think* what you're
describing is something like
data = [
("one", "two", lambda: "12"),
("three", "four", lambda: "34"),
("five", "six", lambda: "56"),
("seven", "eight", lambda: "78"),
]
mapping = dict(
(k, t)
for t in data
for k in t[:2]
)
for test in (
"one",
"two",
"three",
"four",
"five",
"six",
"seven",
"eight"
):
a, b, fn = mapping[test]
print("%s: %r, %r, %r" % (test, a, b, fn()))
-tkc
