I have a list:

my_list = ['element1\t0238.94', 'element2\t2.3904', 'element3\t0139847']

How can I delete the \t and everything after to get this result:

['element1', 'element2', 'element3']

Solution with map and lambda expression:

my_list = list(map(lambda x: x.split('\t')[0], my_list))

I had to split a list for feature extraction in two parts lt,lc:

ltexts = ((df4.ix[0:,[3,7]]).values).tolist()
random.shuffle(ltexts)

featsets = [(act_features((lt)),lc) 
              for lc, lt in ltexts]

def act_features(atext):
  features = {}
  for word in nltk.word_tokenize(atext):
     features['cont({})'.format(word.lower())]=True
  return features
