Python CSV Output Blank Cells -


i trying write exact shell output of python code csv file (including blank fields). python output looks this. have tried head around reason, getting output looks this. 

contractnn develop nn manag   nn order   nn parti   nn suitabl nn supplier nn work    nn

csv output desired

[[(u'contract', 'nn'), (u'develop', 'nn'), (u'manag', 'nn'), (u'order', 'nn'), (u'parti', 'nn'), (u'suitabl', 'nn'), (u'supplier', 'nn'), (u'work', 'nn')]] [[(u'microsoft', 'nn')]] [[(u'hadoop', 'nn')]] [[]] [[(u'python', 'nn'), (u'python', 'nn')]] [[]] [[]]

my python code

import csv import nltk nltk import pos_tag nltk.stem.snowball import snowballstemmer nltk import stem import numpy np  output_file = open('examp_output.csv', 'w') datawriter = csv.writer(output_file)  """bunch of nltk code"""      print [m]      datawriter.writerows(m) output_file.close()

how instead of using csvwriter

import os output_file = open('example.txt','w') #use 'a' instead of 'w' append  instead of overwrite text file if you're doing in loop output_file.write(data_out) os.rename('example.txt', 'example.csv')

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
