dictionary - Comparing values of different python dictionaries with different keys & structures -


this more of theoretical question anything. have 3 dictionaries have different structure/keys values may same. e.g.

dict1 = {u'd':{u'results':[{u'number':'1', u'dispurl':u'www.site.com'}, {u'number':u'2', u'dispurl':u'www.othersite.com'}] }} dict2 = {u'result_page':{u'url':u'www.greatsite.com', u'pos':u'1'}, {u'url':u'www.site.com', u'pos':u'2'}} dict3 = {u'hits':[{u'displayurl':u'www.othersite.com', u'index':u'1'}, {u'displayurl':u'www.site.com', u'index':u'2'}] }

note how dict1 has {u'd': before {u'results':, dict1 , dict3 have different key/values enclosed in square parentheses. note how keys/values layout different in dict1 number key coming before url instead of after in dict2 , dict3, key names being different in each dictionary.

i have 3 large dictionaries , need compare them position of each url scoring purposes. i.e. 

if dict1[www.site.com index] > dict2[www.site.com index]: dict1[www.site.com] score +1

i know code snippet isn't correct it's illustration. want know need dictionaries able perform comparison this? thinking of taking required data each dictionary , putting them 3 new dictionaries uniform keys , structure, or 1 new dictionary. program has computationally quite fast don't know how affect it. of more experienced python programmers want have on this?

the effective way approach convert data canonical {url:value} format.

for example:

dict1 = {data[u'dispurl']:int(data[u'number']) data in dict1[u'd'][u'results']} dict2 = {data[u'url']:int(data[u'pos']) data in dict2[u'result_page']} dict3 = {data[u'displayurl']:int(data[u'index']) data in dict3[u'hits']}

now like

dict1 = {u'www.othersite.com': 2, u'www.site.com': 1} dict2 = {u'www.greatsite.com': 1, u'www.site.com': 2} dict3 = {u'www.othersite.com': 1, u'www.site.com': 2}

and comparison looks like

for url in dict1: if dict1[url] > dict2[url]: #

c++ - Accessing inactive union member and undefined behavior? -

i under impression accessing union member other last 1 set ub, can't seem find solid reference (other answers claiming it's ub without support standard). so, undefined behavior? the confusion c explicitly permits type-punning through union, whereas c++ ( c++11 ) has no such permission. c11 6.5.2.3 structure , union members 95) if member used read contents of union object not same member last used store value in object, appropriate part of object representation of value reinterpreted object representation in new type described in 6.2.6 (a process called ‘‘type punning’’). might trap representation. the situation c++: c++11 9.5 unions [class.union] in union, @ 1 of non-static data members can active @ time, is, value of @ 1 of non-static data members can stored in union @ time. c++ later has language permitting use of unions containing struct s common initial sequences; doesn't permit type-punning. to determine whether union type-punning is allowe...

php - Get uncommon values from two or more arrays -

is there function in php give array of uncommon values 2 or more arrays? for example: $array1 = array( "green", "red", "blue"); $array2 = array( "green", "yellow", "red"); .... $result = function_needed($array1, $array2,...); print_r($result); should give output: array("blue", "yellow", ...); use array_diff , array_merge : $result = array_merge(array_diff($array1, $array2), array_diff($array2, $array1)); here's demo. for multiple arrays, combine callback , array_reduce : function unique(&$a, $b) { return $a ? array_merge(array_diff($a, $b), array_diff($b, $a)) : $b; } $arrays = array( array('green', 'red', 'blue'), array('green', 'yellow', 'red') ); $result = array_reduce($arrays, 'unique'); and here's demo of that.
