to amazing programmers, i know how can sort defaultdict(list) collection such sort order of 1 list (e.g. defaultdict(list)[list1]) applied remaining lists well. perhaps short description/example more useful. if there better way of doing ears. example problem: had .csv file consisting of many columns (different data types) , headerline. using defaultdict(list) import .csv file using: data = defaultdict(list) reader = csv.dictreader(open(filepath, 'r')) (k,v) in row.items(): data[k].append(v) now left defaultdict(list) named 'data' of structure: data = [('vara', <list of n time.struct_time items>), ('varb', <list of n other data type items>)', ('varc', <list of n other data type items>)'] each list (vara, varb, varc) has exact same number of items. assuming vara not ordered, how order data entries based on vara. i know sortorder = [i[0] in sorted(enumerate(data['vara']), key

javascript - parseInt vs unary plus - when to use which -

what differences between line: var = parseint("1", 10); // === 1 and line var = +"1"; // === 1 this jsperf test shows unary operator faster in current chrome version, assuming node.js!? if try convert strings not numbers both return nan : var b = parseint("test" 10); // b === nan var b = +"test"; // b === nan so when should prefer using parseint on unary plus (especially in node.js)??? edit : , what's difference double tilde operator ~~ ? please see this answer more complete set of cases well, here few differences know of: an empty string "" evaluates 0 , while parseint evaluates nan . imo, blank string should nan . +'' === 0; //true isnan(parseint('',10)); //true the unary + acts more parsefloat since accepts decimals. parseint on other hand stops parsing when sees non-numerical character, period intended decimal point . . +'2.3' === 2.3;
