python - Replicate identical tuples to N -

this question has answer here: how create list of repeated tuples in python? 2 answers i have identical tuples of (0, 1) assigned define limits 3 input values: bounds = ((0, 1), (0, 1), (0, 1)) is there pythonic way assign same tuples n inputs? example: bounds = ((0, 1), (0, 1), (0, 1), (0, 1), (0, 1), ...nth(0, 1)) you can multiply sequence n shallow copies of contents: bounds = ((0, 1),) * n this fine tuples of ints or other immutable data structures containing immutable types, cause surprising behavior if use mutable data structures lists - sequence of n references same list, because it's shallow copy. in case, comprehension idiomatic way create n independent objects: mutable_bounds = [[0, 1] _ in range(n)]

matlab - How to recover files that were moved to a single file? -

Image
i tried move multiple files folder, there mistake in matlab code didn't create folder. files moved single file cannot opened or edited. how recover these files? example of mistake: a=strcat('c:\users\foldername'); % name , directory of folder fname=a; % mkdir(fname); % command wasn't executed... movefile('file1',fname); movefile('file2',fname); so file1 , file2 merged in file 'fname', instead of in folder named 'fname'. how file1 , file2 back? thanks in advance! unfortunately, odds may stacked against getting of files, except last one. reason why because movefile doesn't append existing destination file, overwrites it. following give last file (by renaming fname ): movefile(fname, 'file2'); if you're lucky, operating system have options restore previous versions of files/folders . best bet may check , see if folder containing original files has previous versions can open/restore previo

(keeping in mind list may contain large number of elements). also, possible in such can define sort of custom order sorting, if want every third element sorted in descending order. : ['abcd' ,'fghi', 'srqp', 'uxyz'] this 1 liner works: mylist = ['cbad','hfig','qspr','uyxz'] ["".join(sorted(s, reverse=i%2)) i,s in enumerate(mylist)]

i want record audio of webrtc call , have problems these 2 issues: the sample rate of audio should 16 khz. i want send small chunks (eg. 2s long) server. i'm using recordrtc library. when use stereoaudiorecorder can solve issue 1. because it's recording .wav , offers parameter change sample rate 16 khz. can't find way blob of recorder while i'm recording. my second approach use mediastreamrecorder . it's recording webm/opus sample rate of 48 khz , can't find way change this. mediastreamrecorder offers method getinternalrecorder().getarrayofblobs() blobs while recording. the solution doesn't have recordrtc . library , file format fine.
