Let's do an exercise.

See the given file, batman.txt, containing the quotes from famous Hollywood movies.

Our aim is to write a program to find a given word from the file:

Let's write a program to find the particular word from the file. We are making the assumption that the program should be case insensitive, which means it does not matter whether the characters are in uppercase or lowercase.

See the code in findword.py:

word = raw_input("Enter the word ")
word = word.lower()
file_txt = open("batman.txt", "r")
count = 0
for each in file_txt:
    if word in each.lower():
        count = count+1
print "The ", word ," occured ",count, " times"

The program is very easy to understand. Let's see the output of the code:

The program findword.py is working fine.
