i new python. trying input 1 path , use os.walk() search files, , return files' names. want use os.path.getsize() file size, , finally, write them csv file. however, if file name not in english, in chinese, german, french, etc, python cannot recognize , not return size of file. i'd use os.path.getsize(path) (referring example below), not recognize file's name. how can let python recognize file's name , return size of these kind of files? for example: file's name is: "Показатели естественного и миграционного прироста до 2030г.doc" . path="c:\xxxx\xxx\xxxx\Показатели естественного и миграционного прироста до 2030г.doc" if pass unicode input os.walk() file-names unicode well. the following should work you your_base_path = u"c:\\directory" # note unicode root, dirs, files in os.walk(your_base_path): f in files: print os.stat(os.path.join(root, f)).st_size

lets take basic arithmetic operation - modulo i different outputs depending on different languages. python >>> -1 % 12 11 c# var res = -1 % 12; output: res = -1 why seeing such behaviour? ideally i'd output 11 in both cases. also know if can achieve in c#? the premise of question incorrect. % operator in c# not modulus operator, remainder operator, while in python is modulus operator. as eric lippert describes , modulus , remainder same positive numbers, handle negative numbers differently. despite both c# , python having % operator, doesn't mean both represent modulus. it's worth noting other languages, such c++ , java use remainder % operator, not modulus, contributed why c# choose use remainder well. since there isn't lot of consistency in meant % operator, suggest looking in language docs whenever working new language.

in order achieve continuous integration, in book continuous integration: improving software quality , reducing risks, 1 can read 1 of principles behind centralizing software assets on version control system, may these compiled artifacts, libraries, third party components , on. i can understand such statement in case 1 using scm , nothing else. if 1 using tool such nexus? nexus or alike makes such statement obsolete when referring built artifacts? the short answer is: "yes" the longer answer using nexus centralize software assets legitimate, versioned store. more appropriate technologies need compile binaries, scripted technologies favour creating tarballs or better still rpm packages. deployment process incorporates scm system marries software.... more worryingly every person needs install software must have access (credentials) tool.
