Convert a numpy.ndarray to string(or bytes) and convert it back to numpy.ndarray

I\'m having a little trouble here,

I\'m trying to convert a numpy.ndarray to string, I\'ve already done that like this:

randomArray.tostring()
         


        

Answer 1

Imagine you have a numpy array of text like in a messenger

 >>> stex[40]
 array(['Know the famous thing ...

and you want to get statistics from the corpus (text col=11) you first must get the values from dataframe (df5) and then join all records together in one single corpus:

 >>> stex = (df5.ix[0:,[11]]).values
 >>> a_str = ','.join(str(x) for x in stex)
 >>> a_str = a_str.split()
 >>> fd2 = nltk.FreqDist(a_str)
 >>> fd2.most_common(50)
