Iterating through a string word by word

Question

I wanted to know how to iterate through a string word by word.

string = "this is a string"
for word in string:
    print (word)

The above gives an output:

t
h
i
s

i
s

a

s
t
r
i
n
g

But I am looking for the following output:

this
is
a
string

Answer 1

When you do –

for word in string:

You are not iterating through the words in the string, you are iterating through the characters in the string. To iterate through the words, you would first need to split the string into words , using str.split() , and then iterate through that . Example –

my_string = "this is a string"
for word in my_string.split():
    print (word)

Please note, str.split() , without passing any arguments splits by all whitespaces (space, multiple spaces, tab, newlines, etc).

This is one way to do it:

string = "this is a string"
ssplit = string.split()
for word in ssplit:
    print (word)

Output:

this
is
a
string

Using nltk.

from nltk.tokenize import sent_tokenize, word_tokenize
sentences = sent_tokenize("This is a string.")
words_in_each_sentence = word_tokenize(sentences)

You may use TweetTokenizer for parsing casual text with emoticons and such.

Answer 5

s = 'hi how are you'
l = list(map(lambda x: x,s.split()))
print(l)

Output: ['hi', 'how', 'are', 'you']

One way to do this is using a dictionary. The problem for the code above is it counts each letter in a string, instead of each word. To solve this problem, you should first turn the string into a list by using the split() method, and then create a variable counts each comma in the list as its own value. The code below returns each time a word appears in a string in the form of a dictionary.

    s = input('Enter a string to see if strings are repeated: ')
    d = dict()
    p = s.split()
    word = ','
    for word in p:
        if word not in d:
            d[word] = 1
        else:
            d[word] += 1
    print (d)

You can try this method also:

sentence_1 = "This is a string"

list = sentence_1.split()

for i in list:

print (i)
