Starap function exists but it seems there's not such thing as "doublestarmap"
Hello. I have a following question: How come there's no such thing in Python like starmap but which unpacks dicts as kwargs for fuction? For example I have a format string like "{param1}, {param2}" and want to get results passing list of dicts for it's .format(). Of course I can do that with genexpr or some lambda with map. But can you clarify why starmap version of map fuction exists and doublestarmap doesn't? Best Regards.
I don't really understand. You can do: '{a} {b}'.format(**{'a': 1}, **{'b': 2}) Is that what you want?

I need smth like starstarmap('{a} / {b}/ {c}'.format, [{a:1, b:2, c:3}, {a:4, b:5, c:6}, ...]) On 4/10/19 7:48 PM, Anders Hovmöller wrote:

That's def starstarmap(f, it): return (f(**x) for x in it) That looks like a recipe, not a basis function ^^

Seems overly specific. Why not merge the dicts then call formal like normal?

Use the format_map method of str.
list(map('{a} / {b}/ {c}'.format_map, [{'a':1, 'b':2, 'c':3}, {'a':4, 'b':5, 'c':6}])) ['1 / 2/ 3', '4 / 5/ 6']
