for x, word in enumerate(mylist):
    for i, subwords in enumerate(word):
        print i

Totally doesnt work....

What do you guys think?

Answer 1

Use str.split:

>>> mylist = ["Mahon Point retail park", "Finglas","Blackpool Mahon", "mahon point  blanchardstown"] 
>>> for item in mylist:
...     print len(item.split())
...     
4
1
2
3

Answer 2

The simplest way should be

num_words = [len(sentence.split()) for sentence in mylist]

Answer 3

You can use NLTK:

import nltk
mylist = ["Mahon Point retail park", "Finglas","Blackpool Mahon", "mahon point  blanchardstown"]
print(map(len, map(nltk.word_tokenize, mylist)))

Output:

[4, 1, 2, 3]

Answer 4

for x,word in enumerate(mylist):
    print len(word.split())

Answer 5

a="hello world aa aa aa abcd  hello double int float float hello"
words=a.split(" ")
words
dic={}
for word in words:
    if dic.has_key(word):
        dic[word]=dic[word]+1
    else:
        dic[word]=1
dic

Answer 6

We can count the number of a word's ocurrence in a list using the Counter function.

from collection import Counter

string = ["mahesh","hello","nepal","nikesh","mahesh","nikesh"]

count_each_word = Counter(string)
print(count_each_word)

Output:

Counter({mahesh:2},{hello:1},{nepal:1},{nikesh:2})
