Is Python reevaluating arithmetic operations with bignums each time the resut is used? -


okay, trying throw in large number evaluation on python - of order of 10^(10^120)- realized quite huge. anyways, receded 10**10**5 , 10**10**6. checking time difference of 2 brought me strange finding see inefficiency.

the finding when tried cprofile.run("x=10**10**6") took 0.3s , cprofile.run("print 10**10**6") took 40s.

then tried x= 10**10**6 took no time thereafter every time interpreted x (x followed enter) take long time (40s suppose). so, assuming every time interpret x calculates entire value on again.

so question is: isn't extremely inefficient? had declared variable in module, x= 10**10, , every time reference x python interpreter compute value of 10**10 on , on again ?

gory details appreciated.

the value not being recalculated each time print it, long delay see cost of converting large number string displaying.

JQuery Autocomplete without using label, value, id -

is possible have jquery autocomplete work without using conventional id,label,value? for instance, not wish use: [ { "id": "botaurus stellaris", "label": "great bittern", "value": "great bittern" }, { "id": "asio flammeus", "label": "short-eared owl", "value": "short-eared owl" }] but rather: [ { "my_id": "botaurus stellaris", "first_name": "great bittern", "last_name": "great bittern" }, { "my_id": "asio flammeus", "first_name": "short-eared owl", "last_name": "short-eared owl" }] so like, jquery autocomplete takes id,value,label , can make take my_id, first_name, last_name , make jquery autocomplete treat same id,label,value ? this might useful, when don't wish modify data's keys coming datasource, display on jquery autocomplete. ...

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...

JAVA - what is the difference between void and boolean methods? -

i new java. writing wrapper-library in java make functions available in basic-like language. i got stock @ point when noted code not executed in java-library although compiler did not complain (using eclipse). resolved replacing code follows: public void videoquality(int vquality) //did not work into public boolean videoquality(int vquality) //works here complete code-snippets: public void videoquality(int vquality) //did not work {if (vquality==16) { vidquality=16; } else if (vquality==-16) { vidquality=-16; } else if (vquality==0) { vidquality=0; } else vidquality=-16; vitamioext.setvideoquality(vidquality); } public boolean videoquality(int vquality) //works {if (vquality==16) { vidquality=16; } else if (vquality==-16) { vidquality=-16; } else if (vquality==0) { vidquality=0; } else vidquality=-16; vitamioext.setvideoquality(vidquality); return true; } i think void corresponds sub in visual basic while boolean corresponds function. i found odd following code worked using...
