when sqlalchemy returns: {u'age': datetime.timedelta(12045),} how 12045? i've tried str() , strftime() , , bunch of others, nothing works. from docs , use .total_seconds() length of timedelta. note timedelta you've provided showing days value, timedelta includes seconds , microseconds well. if want days, use .days . age = datetime.timedelta(12045) print(age.total_seconds()) # 1040688000.0 print(age.days) # 12045, not full value represented delta

say have large parent string containing many characters. how can insert string between match of characters (and additionally, erase characters between matching characters)? for example, largestring guaranteed contain single set of ###### 's (6 hash characters). how can insert smallstring between it, ending similar (i guess better 'create string', since strings immutable): largestring = "lorem ipsum ###### previous text erased ###### dolor sit amet" smallstring = "foo bar" newstring = "lorem ipsum ###### foo bar ###### dolor sit amet" any ideas? assume use bit of regex... something like >>> import re >>> largestring = "lorem ipsum ###### previous text erased ###### dolor sit amet" >>> smallstring = "foo bar" >>> re.sub(r'(?<=###### ).*(?= ######)', smallstring, largestring) lorem ipsum ###### foo bar ###### dolor sit amet' (?<=###### ) postive b

i worked entity framework several years ago, , may me being bit rusty. have detached entities, in turn have multiple child entities. in case it's person entity , each person has multiple addresses. myperson.firstname="update first name"; //assuming have address in first entry //with appropriate primary keys , foreign key ids, do: myperson.addresses.first().line1="update line 1"; myperson.addresses.add(new address(){line1="weee",line2="aaaa" postal="12345", type="work"}); mydb.person.attach(myperson); mydb.entry(myperson).state=entitystate.modified; mydb.savechanges(); when scenario this, expect first name. updates first name, , expected blanks out other fields (lastname, birthday etc etc) in above code. doesn't create new address person, nor update existing address. i don't recall requiring work database context know how update related entities associated person above. in google searches seem hearin

i have problem persistent footer on page. creating web app jquery mobile. link project site when click add1 button footer updates"order(1)" , increments, when navigate second page see "order" , no number. my question is, how can fix that? i want keep same footer pages. i viewed project site , code has bugs. ill explain 1 one. you using same id name (objednavka) more once. id name must unique in document , not used more once. if want update many elements have same name use class instead. you don't need use pagebeforecreate have multi-page template (many pages) in 1 document , first gets loaded @ pageload. need create navbars @ once update orders , totals simultaneously. to add 1 variable better method use plus plus (myvar++) instead of updating whole order button again includes (order) text when click add 1 use span class="objednavka" next order , update new number there. we don't use $(document).ready(function() {

i've run remove , sort usings matter of course, because seems right thing do. got wondering: why this? certainly, there's benefit clean & compact code. , there must benefit if ms took time have menu item in vs. can answer: why this? compile-time or run-time (or other) benefits removing and/or sorting usings? as @craig-w mentions, there's small compile time performance improvement. the way compiler works, when encounters type, looks in current namespace, , starts searching each namespace using directive in order presented until finds type it's looking for. there's excellent writeup on in book clr via c# jeffrey richter ( http://www.amazon.com/clr-via-4th-developer-reference/dp/0735667454/ref=sr_1_1?ie=utf8&qid=1417806042&sr=8-1&keywords=clr+via+c%23 ) as why ms provided menu option, imagine enough internal developers asking for same reasons mention: cleaner, more concise code.

if swift generic type constraint protocol name, can require 2 types, constrained protocol, same type. example: protocol flier {} struct bird : flier {} struct insect: flier {} func flocktwotogether<t:flier>(f1:t, f2:t) {} the function flocktwotogether can called bird , bird or insect , insect, not bird , insect. limitation want. far, good. however, if try same thing class name, doesn't work: class dog {} class noisydog : dog {} class wellbehaveddog: dog {} func walktwotogether<t:dog>(d1:t, d2:t) {} the problem can call walktwotogether wellbehaveddog , noisydog. want prevent. there 2 questions here: is there way walktwotogether can't called wellbehaveddog , noisydog? is bug? ask because if can't use generic this, hard see why useful generic constraint class name @ all, since same result normal function. not answer, per se, more data perhaps... problem when call: walktwotogether(noisydog(), wellbehaveddog()) swift can treat bo

if delete pointer first time, release memory , assign null pointer. if delete pointer (with null value) second time, nothing happens, , no error throws out. then why isn't destructor designed delete of pointer, manuall call destructor of object, , assign object, null. destructor can called many times without error? [update] meant assign null explicitly pointer. the whole purpose of constructors , destructors avoid manual calling of destructor. it's designed objects automatically destroyed when no longer in use. makes harder programmer accidentally forget delete object; or use object has been deleted.

i have excel file combobox (name = "combobox1"). after running script (basically pasting selected value in "the next row" of column) want focus reset on combobox @ end of script, doing allowing me type next entry in combobox without having click on combobox text field first. this job in excel 2013 have working in 2007 well: combobox1.activate anyone idea? or: can replace combobox in-cell dropdown list (data validation) , same data validation 1 have in combobox @ moment, have issue: combobox can choose have dropdown list active, in-cell data validation not case, @ least not if want able type in cell after list shown alt+up or application.sendkeys "%{up}" any idea here?

in uml class diagram, technically correct have 2 possible compistion relationships leading 1 class? i.e. have inventory class, has composition of inventory class. want have same relationship container class taking place of inventory. so, can have 2 compositions, or need turn these aggregations? you can have many composite associations on class level. each instance can part of 1 composition @ specific moment in time. uml superstructure says: if whole has aggregationkind = composite part can included in @ 1 composite @ time this article wrote tries explain difference: uml composition vs aggregation vs association

i started using datastore, i'm still not sure few things. i have fallowing entities: property: {id, number, name, long, lat} address: {name, postcodetype} city: {name} country: {name} user: {name, username} so logic behind user have multiple properties , means property hold user key . as described above property has properties, not sure on how associate address city , country . i think solution store keys 3 entities in property entity . type property struct { id int64 `json:"id" datastore:"-"` number int8 `json:"number"` name string `json:"name"` long float64 `json:"long"` lat float64 `json:"lat"` addresskey *datastore.key citykey *datastore.key countrykey *datastore.key userkey *datastore.key createdat time.time } is attempt above start or need different. a list of countries changes, programmers use enum (or go
