Write a Python program called wdcount.py which uses a dictionary to count the number of occurrences of each word (ignoring case)
Art [367]

The program is an illustration of loops.

<h3>What are loops?</h3>

Loops are program statements used to perform repetition

<h3>The wordcount.py program</h3>

The program written in Python, where comments are used to explain each line is as follows

# This opens the file in read mode

text = open("myFile.txt", "r")

# This creates an empty dictionary

d = dict()

#This iterates through the text

for line in text:

# This splits the line into words, after removing leading & trailing spaces, and newline characters

words = line.strip().lower().split(" ")

# This iterates through all the words

for word in words:

 # The following if condition counts the occurrence of each word

 if word in d:

  d[word] = d[word] + 1

 else:

  d[word] = 1

#This prints the words and their frequencies, in descending order

for w in sorted(d, key=d.get, reverse=True):

   print(w, d[w])
