python - Tree of trees? Table of trees? What kind of data structure have I created? -


i creating python module creates , operates on data structures store lots of semantically tagged data , metadata real experiments. in experiment have:

  • subjects
  • treatments
  • replicates

enclosing these 3 categories experiment, , combinations of 3 categories calling "units". there no inherently correct hierarchy between 3 (table-like) analyses useful think of permutation of 3 hierarchy,

e.g. (subjects-->(treatments-->(replicates)))

or

(replicates-->(treatments-->(subjects)))

moreover, when collecting data, files copy-pasted folder on desktop, data @ least coming in tree. have thought lot hierarchy "better" keep coming use cases of 6 possible permutations. want module flexible in user can think of experiment or collect data using whatever hierarchy, table, hierarchy-table hybrid makes sense them.

also "units" or (table entries) containers arbitrary amounts of data (bytes gigabytes, whatever ideally) of organizational complexity. why didn't think relational database approach way go , nosql type solution makes more sense. have problem of how order 3 categories if none "correct".

so question multifaceted data structure?

does sort of fluid data structure or set of algorithms exist inter-convert or produce structured views?

the short answer hdf5 addresses these common concerns , suggest it. http://www.hdfgroup.org/hdf5/

in python: http://docs.h5py.org/en/latest/high/group.html http://odo.pydata.org/en/latest/hdf5.html

will help.

utf 8 - split utf-8 string into bytes in python -

i trying split utf-8 string bytes in python 3. problem is, when use bytearray, byte, encode etc functions array size of element 14 bytes, not 1 byte expected. need split text file sequence of bytes , send them byte after byte using sockets. tried this: infile = open (file, "r") str = infile.read() byte_str = bytes(str, 'utf-8') print("size of byte_str",sys.getsizeof(byte_str[0])) print gives me 14, need 1... suggestion? quoting official documentation : sys.getsizeof(object[, default]) return size of object in bytes. object can type of object. built-in objects return correct results, not have hold true third-party extensions implementation specific. only memory consumption directly attributed object accounted for, not memory consumption of objects refers to. if given, default returned if object not provide means retrieve size. otherwise typeerror raised. getsizeof() calls object’s __sizeof__ method , adds
