whats best way regex search , replace instances of array_key_exists() more efficient isset() ? please, no donald knuth quotes regarding optimizations , yes, i'm aware of differences between 2 functions . this i'm using in netbeans search , replace: search for: array_key_exists\s*\(\s*'([^']*)'\s*,([^)]*)\) replace with: isset($2['$1']) it works , changing this: array_key_exists('my_key',$my_array) to isset($my_array['my_key']) but doesn't pick instances this: array_key_exists($my_key,$my_array) not elegant solution, adding current regex find both types of search criteria. array_key_exists\s*(\s*'|$['|\s]\s*,([^)]*))

normally it's possible put arbitrary objects numpy arrays: class foo(object): pass np.array([ foo() ]) >>> array([<__main__.foo object @ 0x10d7c3610>], dtype=object) however, appears objects implementing __len__ , __getitem__ "unpacked" automatically: class foo(object): def __len__(self): return 3 def __getitem__(self, i): return i*11 np.array([ foo() ]) >>> array([[0, 11, 22]]) is there way stop numpy unpacking objects in way? want put objects numpy array , have them stored objects themselves, without being unpacked. desired behavior is: class foo(object): def __len__(self): return 3 def __getitem__(self, i): return i*11 np.array([ foo() ]) >>> array([<__main__.foo object @ 0x10d7c3610>], dtype=object) now understand duck typing idea implies numpy should unpack looks list. perhaps it's possible mark class foo in way tell numpy not unpack it? example, abc like: numpy.nonenumerable.register...

as know, can define function type: typedef void (fn)(void); and can define function pointer type: typedef void (*pfn)(void); there 2 functions. first function's parameter type function, , other function pointer: void a(fn fn1) { fn1(); } void b(pfn fn1) { fn1(); } i implement function callback: void callback(void) { printf("hello\n"); } and pass argument , b: int main(void) { a(callback); b(callback); return 0; } both , b work well, , print "hello" . so want know difference between defining function type , function pointer type? or actually, same? given abuse can use function pointers ( &func , func , *func , **func , … end same value function func ), there few practical differences between two. can use fn * indicate pointer function, not trivial transform. however, here's mild adaptation of code, using non-parameter variable of type pfn , attempting (unsuccessfully) use non-paramete...
