python - Combine dictionaries based on key value -


how combine rows of dictionaries having same keys. instance if have 

my_dict_list = [{'prakash': ['confident']},  {'gagan': ['good', 'luck']},  {'jitu': ['gold']},  {'jitu': ['wins']},  {'atanu': ['good', 'glory']},  {'atanu': ['top', 'winner','good']}]

my objective 

my_new_dict_list = [{'prakash': ['confident']},  {'gagan': ['good', 'luck']},  {'jitu': ['gold','wins']},  {'atanu': ['good', 'glory','top', 'winner','good']}]

how do in python?

edit: dictionaries in final list must contain repeated values if present in starting list.

a minimalist approach using defaultdict:

from collections import defaultdict  my_dict_list = [{'prakash': ['confident']},  {'gagan': ['good', 'luck']},  {'jitu': ['gold']},  {'jitu': ['wins']},  {'atanu': ['good', 'glory']},  {'atanu': ['top', 'winner','good']}]  merged_dict = defaultdict(list) d in my_dict_list:     key, value in d.items():         merged_dict[key].extend(value) result = [{key:value} key, value in merged_dict.items()]  print(result)

output

[{'prakash': ['confident']},  {'gagan': ['good', 'luck']},  {'atanu': ['good', 'glory', 'top', 'winner', 'good']},  {'jitu': ['gold', 'wins']}]

c# - Check Keyboard Input Winforms -

i wondering if instead of doing this protected override void onkeydown(keyeventargs e) { if (e.keycode == keys.a) console.writeline("the key down."); } i set bool method , this: if(keydown(keys.a)) // whatever here i've been sitting here ages trying figure out how it. can't wrap head around it. in case wondering, plan call bool inside different method, check input. since want perform action after pressing key, using keydown event enough. but in cases suppose want check if specific key down in middle of process, can use getkeystate method way: [dllimport("user32.dll", charset = charset.auto, exactspelling = true)] public static extern short getkeystate(int keycode); public const int key_pressed = 0x8000; public static bool iskeydown(keys key) { return convert.toboolean(getkeystate((int)key) & key_pressed); } you should know, each time check key state using example iskeydown(keys.a) method returns true if ke...
