i want make while loop kind of this list=[] while x in range(r): list-x="something" where each time loop begins makes new list number (x). if loops on 5 times there different lists: list(1) list(2) list(3) list(4). ' is possible? you able vars() function: for in range(5): list_name = ''.join(['list', str(i)]) vars()[list_name] = [] you can reference each list: print(list1) --> [] print(list2) --> [] etc... you can achieve using locals() or globals() functions below: for in range(5): locals()['list{}'.format(i)] = [] hope helps!

suppose have theorem: theorem non_ascii_thm_name: "true" simp i want define ascii name non_ascii_thm_name notation command. example, this: notation non_ascii_thm_name ("ascii_thm_name") the isar commands notation , abbreviation can used constants. there isar command allows me to this? preferably, want isar command provide synonym. example, if use sledgehammer , preferable there exist 1 theorem, non_ascii_thm_name , sledgehammer not using additional fact ascii_thm_name . a partial solution use command: lemmas ascii_thm_name = non_ascii_thm_name this define new theorem called ascii_thm_name same non_ascii_thm_name . there unfortunately no guarantee tools such find_theorems use new name, instead use own heuristics determining "best" name output user. an alternative synonym lemmas theorems , though former considered more standard approach.

shared header. i can this: const bool kactivateplayground=false; works fine when included among multiple files. i cannot this: const char * kactiveplayground = "kiddiepool"; results in error: duplicate symbols. but works: static const char * kactiveplayground = "kiddiepool"; why static needed const char * not const bool ? additionally, thought static not necessary since const static implicity? in c++, const variables default have static linkage, while non- const variables have external linkage. the reason multiple definitions error that const char * kactiveplayground = "kiddiepool"; creates variable external linkage. hey wait, didn't const variables default static linkage? yes did. kactiveplayground not const . non- const pointer const char . this work expect: const char * const kactiveplayground = "kiddiepool";

(does python support preparation , re-use of prepared statements postgresql?) for postgresql question, answer there no python-specific way handle prepared statements @ least of last october (i not python programmer common across languages). postgresql offers sql-language way language can use prepared statements if sql queries can executed. code examples on how in python, see http://initd.org/psycopg/articles/2012/10/01/prepared-statements-psycopg/ there couple of major caveats though. 1 of them prepared statements planned on first run, , plan re-used. works great queries same plan uniformly required (say, simple inserts) causes problems parameters might change enough new plans might required. following ok in cases(there still nasty cor...

so, have calayer , has mask & want add border around layer's mask. example, have set triangle mask layer , want have border around layer. can please me solve problem? some suggestions: use opaque shadow instead of border (you have blurred effect). create layer, set background color color want border, mask mask bigger 1 have simulate border width, , put centered behind layer (may not work every shape). do morphological operation on mask image calculate border, instance vimagedilate family of functions (more complicated, , may run performance problems). if know shape , can described mathematically, draw , stroke explicitly core graphics functions. or, in same case (shape known mathematically), use cashapelayer draw border.
