i new python, , have question how use python read , write csv files. file contains germany, french, etc. according code, files can read correctly in python, when write new csv file, unicode becomes strange characters.

the data like: enter image description here

and code is:

import csv  f=open('xxx.csv','rb') reader=csv.reader(f)  wt=open('lll.csv','wb') writer=csv.writer(wt,quoting=csv.quote_all)  wt.close() f.close()

and result like: enter image description here

would please tell me should solve problem? thank much!

make sure encode , decode appropriate.

this example roundtrip example text in utf-8 csv file , out demonstrate:

# -*- coding: utf-8 -*- import csv  tests={'german': [u'straße',u'auslösen',u'zerstören'],         'french': [u'français',u'américaine',u'épais'],         'chinese': [u'中國的',u'英語',u'美國人']}  open('/tmp/utf.csv','w') fout:     writer=csv.writer(fout)         writer.writerows([tests.keys()])     row in zip(*tests.values()):         row=[s.encode('utf-8') s in row]         writer.writerows([row])  open('/tmp/utf.csv','r') fin:     reader=csv.reader(fin)     row in reader:         temp=list(row)         fmt=u'{:<15}'*len(temp)         print fmt.format(*[s.decode('utf-8') s in temp])

prints:

german         chinese        french          straße         中國的            français        auslösen       英語             américaine      zerstören      美國人            épais

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 ...
