Program to count the occurence of each word within a paragraph

The text file (paragraph.txt) is as follows:

 

Lorem Ipsum is simply dummied text of the printing and typesetting
industry. Lorem Ipsum has been the industry's standard dummy
text ever since the 1500s when an unknown printer took a galley
of type and scrambled it to make a type specimen book. It has
survived not only five centuries, but also the leap into electronic
typesetting, remaining essentially unchanged. It was popularised in
the 1960s with the release of Letraset sheets containing Lorem
Ipsum passages, and more recently with desktop publishing software
like Aldus PageMaker including versions of Lorem Ipsum.

The program is as follows:

 

# Owner : TutorialsInhand Author : Devjeet Roy

file = open('paragraph.txt','r')

word_dict = dict()

for i in file:
    words = i.split(" ")
    for j in words:
        if '\n' in j:
            j = j.replace('\n','')
        word_dict[j] = word_dict.get(j, 0) + 1

print("The word dictionary is:\n",word_dict)

The output is as follows:

Few important tips about the program

1. We use the open() function to open() a file in Python. The "r" argument signifies that the file has been opened in the reading mode.

2. We create a blank dictionary word_dict = {}

3. The i variable helps us to iterate the file, line by line.

4. We split the line that i variable points to, spacewise.

5. Now, we iterate over each word to count it. If the word is already present in the dictionary, we increment its count by 1, else we initialize it and set it to 1.

6. We check for new line character "\n" and remove them from the words.
