In this article, we will try to see how we count the words in a paragraph using two different approaches.
Let’s take a text file which contains the summary of a screenplay of a movie taken from Wikipedia and see how we can perform the task.

Reading the File

FileName = ("script_file.txt")
with open(FileName, 'r') as file:
    lines =
The format is structured so that one page equates to roughly one minute of screen time, though this is only used as a ballpark estimate and often bears little resemblance to the running time of the final movie.[1] The standard font is 12 point, 10 pitch Courier Typeface.[2]

The major components are action (sometimes called "screen direction") and dialogue. The action is written in the present tense and is limited to what can be heard or seen by the audience, for example descriptions of settings, character movements, or sound effects. The dialogue is the words the characters speak, and is written in a center column.

Unique to the screenplay (as opposed to a stage play) is the use of slug lines. A slug line, also called a master scene heading, occurs at the start of every scene and typically contains three pieces of information: whether the scene is set inside (interior/INT.) or outside (exterior/EXT.), the specific location, and the time of day. Each slug line begins a new scene. In a "shooting script" the slug lines are numbered consecutively for ease of reference.

Method 1)  

How to count words Using nltk?

Here, we will see how we can use nltk package to count the words in the given text file.
Let’s take an example
import nltk
FileName = ("script_file.txt")
with open(FileName, 'r') as file:
    lines = 
    nltk_tokens = nltk.word_tokenize(lines)
    print("Number of Words: " , len(nltk_tokens))
['The', 'format', 'is', 'structured', 'so', 'that', 'one', 'page', 'equates', 'to', 'roughly', 'one', 'minute', 'of', 'screen', 'time', ',', 'though', 'this', 'is', 'only', 'used', 'as', 'a', 'ballpark', 'estimate', 'and', 'often', 'bears', 'little', 'resemblance', 'to', 'the', 'running', 'time', 'of', 'the', 'final', 'movie', '.', '[', '1', ']', 'The', 'standard', 'font', 'is', '12', 'point', ',', '10', 'pitch', 'Courier', 'Typeface', '.', '[', '2', ']', 'The', 'major', 'components', 'are', 'action', '(', 'sometimes', 'called', '``', 'screen', 'direction', "''", ')', 'and', 'dialogue', '.', 'The', 'action', 'is', 'written', 'in', 'the', 'present', 'tense', 'and', 'is', 'limited', 'to', 'what', 'can', 'be', 'heard', 'or', 'seen', 'by', 'the', 'audience', ',', 'for', 'example', 'descriptions', 'of', 'settings', ',', 'character', 'movements', ',', 'or', 'sound', 'effects', '.', 'The', 'dialogue', 'is', 'the', 'words', 'the', 'characters', 'speak', ',', 'and', 'is', 'written', 'in', 'a', 'center', 'column', '.', 'Unique', 'to', 'the', 'screenplay', '(', 'as', 'opposed', 'to', 'a', 'stage', 'play', ')', 'is', 'the', 'use', 'of', 'slug', 'lines', '.', 'A', 'slug', 'line', ',', 'also', 'called', 'a', 'master', 'scene', 'heading', ',', 'occurs', 'at', 'the', 'start', 'of', 'every', 'scene', 'and', 'typically', 'contains', 'three', 'pieces', 'of', 'information', ':', 'whether', 'the', 'scene', 'is', 'set', 'inside', '(', 'interior/INT', '.', ')', 'or', 'outside', '(', 'exterior/EXT', '.', ')', ',', 'the', 'specific', 'location', ',', 'and', 'the', 'time', 'of', 'day', '.', 'Each', 'slug', 'line', 'begins', 'a', 'new', 'scene', '.', 'In', 'a', '``', 'shooting', 'script', "''", 'the', 'slug', 'lines', 'are', 'numbered', 'consecutively', 'for', 'ease', 'of', 'reference', '.']

Number of Words:  223

Method 2) 

How to count words using split function of python?

This is another approach to count numbers of words in the given text file using python split() functions.
Let’s see it with an example
FileName = ("script_file.txt")
with open(FileName, 'r') as file:
    lines_in_file =
    print lines_in_file.split()
    print("Number of Words: ", len(lines_in_file.split()))
['The', 'format', 'is', 'structured', 'so', 'that',
'one', 'page', 'equates', 'to', 'roughly', 'one', 'minute', 'of', 'screen',
'time,', 'though', 'this', 'is', 'only', 'used', 'as', 'a', 'ballpark',
'estimate', 'and', 'often', 'bears', 'little', 'resemblance', 'to', 'the',
'running', 'time', 'of', 'the', 'final', 'movie.[1]', 'The', 'standard',
'font', 'is', '12', 'point,', '10', 'pitch', 'Courier', 'Typeface.[2]', 'The',
'major', 'components', 'are', 'action', '(sometimes', 'called', '"screen',
'direction")', 'and', 'dialogue.', 'The', 'action', 'is', 'written', 'in',
'the', 'present', 'tense', 'and', 'is', 'limited', 'to', 'what', 'can', 'be',
'heard', 'or', 'seen', 'by', 'the', 'audience,', 'for', 'example',
'descriptions', 'of', 'settings,', 'character', 'movements,', 'or', 'sound',
'effects.', 'The', 'dialogue', 'is', 'the', 'words', 'the', 'characters',
'speak,', 'and', 'is', 'written', 'in', 'a', 'center', 'column.', 'Unique',
'to', 'the', 'screenplay', '(as', 'opposed', 'to', 'a', 'stage', 'play)', 'is',
'the', 'use', 'of', 'slug', 'lines.', 'A', 'slug', 'line,', 'also', 'called',
'a', 'master', 'scene', 'heading,', 'occurs', 'at', 'the', 'start', 'of', 'every',
'scene', 'and', 'typically', 'contains', 'three', 'pieces', 'of',
'information:', 'whether', 'the', 'scene', 'is', 'set', 'inside',
'(interior/INT.)', 'or', 'outside', '(exterior/EXT.),', 'the', 'specific',
'location,', 'and', 'the', 'time', 'of', 'day.', 'Each', 'slug', 'line',
'begins', 'a', 'new', 'scene.', 'In', 'a', '"shooting', 'script"',
'the', 'slug', 'lines', 'are', 'numbered', 'consecutively', 'for', 'ease',
'of', 'reference.']
