I am working on a dictionary sorting problem just like the one in the email thread at the bottom of this message. My question about their solution is: In these lines: lst.sort(lambda m, n: cmp(m.get(field), n.get(field))) where field is either 'name' or 'size'.
What is "n:" and what is "lambda m" ?
#!/usr/bin/python
lst = [{"foo": 6, "bar": 10}, {"foo": 1, "bar": 2}] field = "foo"
sort_func = lambda m, n: cmp(m.get(field), n.get(field))
lst.sort(sort_func)
print sort_func(lst[0], lst[1]) print lst
lambda creates a nameless function. _______________________________________________ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor
