Sorting by nested dictionary in Python dictionary -

-

i have below structure

{     'searchresult' : [{             'resulttype' : 'station',             'ranking' : 0.5         }, {             'resulttype' : 'station',             'ranking' : 0.35         }, {             'resulttype' : 'station',             'ranking' : 0.40         }     ] }

and want get

{     'searchresult' : [{             'resulttype' : 'station',             'ranking' : 0.5         }, {             'resulttype' : 'station',             'ranking' : 0.4         }, {             'resulttype' : 'station',             'ranking' : 0.35         }     ] }

tried code without success

result = sorted(result.items(), key=lambda k: k[1][0][1]["ranking"], reverse=true)

if okay changing objects in-place. 

a = {     'searchresult' : [{                        'resulttype' : 'station',                        'ranking' : 0.5                       }, {                        'resulttype' : 'station',                        'ranking' : 0.35                       }, {                       'resulttype' : 'station',                       'ranking' : 0.40                       }]   }  a["searchresult"].sort(key=lambda d: d["ranking"], reverse=true)

or can make deep copy keep original

from copy import deepcopy   srt_dict = deepcopy(a) srt_dict["searchresult"].sort(key=lambda d: d["ranking"], reverse=true)

mysql - FireDac error 314 - but DLLs are in program directory -

-
i getting when trying access mysql database : [firedac][phys][mysql]-314. cannot load vendor library [libmysql.dll or libmysqlld.dll] this did not happen (unchanged) code, however, have upgraded windows 10 , had reinstall delphi xe8, system configuration matter. in order try solve problem, copied both of files c:\windows\sysytem32. when did not seem work, copied them \win32\debug, generated .exe resides. i imagine doing rather stupid, can't see what. the proper solution place driver file (eg., libmysql.dll ) in application's folder, or place installation location in fddrivers.ini file: [mysql] vendor=<folder>\libmysql.dll (recent versions of documentation seem use vendorlib instead of vendor in ini file.) see rad studio documentation topics configuring drivers (firedac) , connect mysql server (firedac) more information.

so per documentation https://developer.github.com/v3/repos/releases/#list-releases-for-a-repository get /repos/:owner/:repo/releases should list relases , https://api.github.com/repos/jquery/jquery/releases should list releases in jquery project , not , why ? because repository doesn't have releases. has tags github presenting in releases page. for more clear example, see: https://github.com/hashicorp/terraform/releases which has both releases , tags showing on page, api shows releases: https://api.github.com/repos/hashicorp/terraform/releases
