object oriented python 3 input error -


i'm working python 3.4 on debian 8.5 linux. i'm working "learn python 3 hard way" , i'm working section running test (via nosetests). have code (which include in full) , it's giving me error on statement should valid, i'm assuming it's not liking how i've set statement up. it's on "class prompt" section:

class prompt(object):     prompt = input("> ")

the idea code prompt 1 time and: call later on easier coding, nose keeps responding :

typeerror: bad argument type built-in operation

i'll include full error test well.

i'm looking see if in fact, i'm calling prompt incorrectly , if so, i'd appreciate nudge in right direction, not full solution ( learn better way :) ) thanks!

thank again !

i can't reproduce error messages here's see:

this definition strange:

class prompt(object):     prompt = input("> ")

when file run or imported, prompts input that's thrown away. since don't invoke feature, it's hard know how meant used. here's guess @ implementation:

class prompt():     @staticmethod     def input():         return input("> ")

usage

>>> x = prompt.input() > goat >>> x 'goat' >>>

beyond that, there other problems program: function has unreachable code:

def opening_room(self):     return self.next_     room(self.start_room)

anything after return never executed. there's no import or code in file define atr() is. additionally, there seem indentation issues (e.g. none of class map() methods indented) , static/class methods defined instance methods.

you might want test smaller chucks of code build larger ones.

Is there a better way to structure post methods in Class Based Views -

i'm using class based views in django , never specify url in ajax calls , omit action parameter in form because know these requests go through post method of class based view. notice view - profile page make many requests depending on user updating on page - post method become convoluted , if/else mess example: def post(self, request, *args, **kwargs): # handle user changing available date if request.post.get('availabledate') != none: self.updateavailabledate(request) return jsonresponse({'result':'success'}) if request.post.get('newprojectname') != none: creative_user = creativeuserprofile.objects.get(id = request.user.id) project = project.create_project(creative_user, request.post['newprojectname']) project.save() return jsonresponse({'projectid': project.id }) if request.post.get('projectimage') != none , request.files['file']: proj...

performance - Why is XCHG reg, reg a 3 micro-op instruction on modern Intel architectures? -

i'm doing micro-optimization on performance critical part of code , came across sequence of instructions (in at&t syntax): add %rax, %rbx mov %rdx, %rax mov %rbx, %rdx i thought had use case xchg allow me shave instruction , write: add %rbx, %rax xchg %rax, %rdx however, dimay found agner fog's instruction tables , xchg 3 micro-op instruction 2 cycle latency on sandy bridge, ivy bridge, broadwell, haswell , skylake. 3 whole micro-ops , 2 cycles of latency! 3 micro-ops throws off 4-1-1-1 cadence , 2 cycle latency makes worse original in best case since last 2 instructions in original might execute in parallel. now... cpu might breaking instruction micro-ops equivalent to: mov %rax, %tmp mov %rdx, %rax mov %tmp, %rdx where tmp anonymous internal register , suppose last 2 micro-ops run in parallel latency 2 cycles. given register renaming occurs on these micro-architectures, though, doesn't make sense me done way. why wouldn't register renamer ...
