Split function to split sentence into words

[fellya]

Hi,

i don't have enough experience in writing codes in Python but now i'm trying to see how i can start using Python.
I've tried to write a simple program that can display a sentence. now my problem is how to write a code using split function to split that sentence into words then print out each word separately. let me give u an example:

>>>sentence=" My question is to know how to write a code in Python"

then the output of this sentece must give:

sentence[1]=My
sentence[2]=question
sentence[3]=is
sentence[4]=to
sentence[5]=know
......
.......

Can someone help me in this?

Always check the documentation, for something interesting. In this case, look at possible string methods ( http://www.python.org/doc/2.5.2/lib/string-methods.html ) and you will see a split function. Here’s a quick example.

>>> sent = "Jack ate the apple."
>>> splitsent = sent.split(' ')
>>> splitsent
['Jack', 'ate', 'the', 'apple.']

Simple as that.

thank you for the help but the question is not fully answered! with this program it will split the sentence but i would like the output to be lets say if we have a= jack ate the apple, i would like the output to be:
a[0]=jack
a[1]=ate
a[2]=the
a[3]=apple

can you please see if its possible to get the above output?

The answer is: string formatting!

Example:

>>> sentence = "The dog ate my homework"
>>> for i,word in enumerate(sentence.split()):
...     print "Word #%d: %s" % (i, word)
...     
Word #0: The
Word #1: dog
Word #2: ate
Word #3: my
Word #4: homework
>>>

thank you for the help, but as u can see with the output below when i do the command sentence[0] to show me the first word it is showing me "T" this is not what i want!!! for me i would like to see if i type the command sentence[0]; to display "The" and if i type again sentence[1]; it has to give me "dog"


can you plz help!

>>> sentence="The dog ate my homework"
>>> for i, word in enumerate(sentence.split()):
...             print " word #%d: %s" % (i,word)
...
 word #0: The
 word #1: dog
 word #2: ate
 word #3: my
 word #4: homework
>>> sentence[0]
'T'
>>> sentence[1];
'h'
>>>

How about this?

>>> split_sentence = sentence.split()
>>> split_sentence[0]
'The'
>>> split_sentence[1]
'dog'
>>>

hi, i have another question related to the above:
I have created a file of more than 100 sentences in it then i saved it with extension .py , then i'm using the operations to open the file which are:

f=open("example.py")
try:
    for line in f:
                    print line
finally:
          f.close()
 

so after using the above commands im able to open my file. Now i know how to split a sentence into words, the problem comes now how can i do it on a file containing more than 100 sentences in it? with 1 or 2 senteces i can write the sentences and split them, now how about a file with many sentences?

can someone help me?

Please use code tags around code. It will make your code much easier to read.

[CODE]..code goes here..[/CODE]

In your code, you are iterating on each line in the file. Each iteration, the variable line represents a sentence. Do you want to save the sentence in a list? What do you want to do with 100 sentences?

The following will save a list of lists. You can access each word by list index.

lineList = [line.strip().split() for line in open("your_file").readlines()]
# print the first word in the first line.
print lineList[0][0]

i dont need to save a sentence in a list. what i want to do is : i take a document which has like any number of sentences then by using Python i would like to split the document of any number of sentences into words where each word has a number e.g., word1=the, word2= apple ect. then by this output i will use an other program that can help me to identify if word1 is a noun or not and son on. Brief after getting all the words in a document , I will try to identify only noun and extract only nouns from the doc.
