Given a file with text paragraphs, print the count of unique words. (the logic should be case-insensitive) code example

Example: Python Program to Count the Occurrences of a Word in a Text File

#get file object reference to the file
file = open("C:\workspace\python\data.txt", "r")
#read content of file to string
data = file.read()
#get number of occurrences of the substring in the string
occurrences = data.count("python")
print('Number of occurrences of the word :', occurrences)
