why python json.dumps complains about ascii decoding? -

-

i have following lines in code

outs = codecs.getwriter('utf-8')(sys.stdout) # djson contains json message non-ascii chars outs.write(json.dumps(djson,encoding='utf-8', ensure_ascii=false, indent=indent_val))

i getting following exception:

    outs.write(json.dumps(djson,encoding='utf-8', ensure_ascii=false, indent=indent_val))     file "/usr/lib/python2.7/json/__init__.py", line 238, in dumps          **kw).encode(obj)     file "/usr/lib/python2.7/json/encoder.py", line 204, in encode          return ''.join(chunks)     unicodedecodeerror: 'ascii' codec can't decode byte 0xc3 in position 27: ordinal not in range(128)

i through specifying encoding='utf-8' in json.dumps statement, avoid type of problem. why still getting error?

my guess djson object not contain pure unicode contains mix of unicode , strings encoded utf-8 e.g. fails

>>> d = {u'name':u'पाइथन'.encode('utf-8')} >>> json.dumps(d, encoding='utf-8', ensure_ascii=false) traceback (most recent call last):   file "<stdin>", line 1, in <module>   file "/system/library/frameworks/python.framework/versions/2.7/lib/python2.7/json/__init__.py", line 238, in dumps     **kw).encode(obj)   file "/system/library/frameworks/python.framework/versions/2.7/lib/python2.7/json/encoder.py", line 204, in encode     return ''.join(chunks) unicodedecodeerror: 'ascii' codec can't decode byte 0xe0 in position 1: ordinal not in range(128)

but works (everything unicode)

>>> d = {u'name':u'पाइथन'} >>> json.dumps(d, encoding='utf-8', ensure_ascii=false) u'{"name": "\u092a\u093e\u0907\u0925\u0928"}

though works (everything string)

>>> d = {'name':u'पाइथन'.encode('utf-8')} >>> json.dumps(d, encoding='utf-8', ensure_ascii=false) '{"name": "\xe0\xa4\xaa\xe0\xa4\xbe\xe0\xa4\x87\xe0\xa4\xa5\xe0\xa4\xa8"}'

c++ - Clear the memory after returning a vector in a function -

-
i have function processes , stores lot of data in , returns results vector of class. amount of data stored in function tremendous , want clear storage memory of function after finished job. necessary (does function automatically clear memory) or should clear memory function? update: vector<customers> process(char* const *filename, vector<int> id) { vector<customers> list_of_customers; (perform actions) return list_of_customers; } variables defined locally within function automatically released @ end of function scope. destructors objects called, should free memory allocated objects (if objects coded correctly). example of such object std::vector . anything you've allocated new must have corresponding delete release storage. try avoid doing own allocation , use raii instead, i.e. containers or smart pointers.

erlang - Saving a digraph to mnesia is hindered because of its side-effects -

-
updated the digraph library in erlang implements data type side-effectful. each operation on data type saves new state in ets table -- instead of returning altered version of itself, more common in functional languages. the problem usage perspective, impedes effort store or pass around state in convenient way requiring me first "collect" state before can start juggle around. the closest solution have seen far serializer/deserializer , these have drawback tied current structure of digraphs instead of operating on abstract type -- prevents future proof solution. update pascal pointed out serializer utilizes interface of digraph, , hence eliminates drawback mentioned above. better, albeit still inconvenient, see no better alternative. what recommendation on how store digraphs? should go different data type altogether? thanks. i not sure understand concern. fact digraph stored in ets transparent in user interface, might want chnge either exchange digr...
