Question

I am looking at a functional way to do the following:

lst = []
for k, v in dict.iteritems():
    lst.append(my_class(k, v))
return lst

Something akin to

imap(lambda (k,v): my_class(k, v), [...] dict [...]) 

would be ideal but clearly does not work.

How could I do it?

Answer 1

Let d be a dict and f a callable, and given the starmap function, the second code could be written:

from itertools import starmap
starmap(f, d.iteritems())

Or to match your code: starmap(my_class, dict.iteritems())

And to actually answer your question, the functional way would be:

return list(starmap(my_class, dict.iteritems))
