Find the most repeated word in a text file

# Python program to find the most repeated word 
# in a text file

# A file named "gfg", will be opened with the  
# reading mode.
file = open("gfg.txt","r")

frequency = 0  
words = []

# Traversing file line by line 
for line in file:
    
    # splits each line into
    # words and removing spaces 
    # and punctuations from the input
    line_word = line.lower().replace(',','').replace('.','').split(" ");  
    
    # Adding them to list words
    for w in line_word:  
        words.append(w);  
        
# Finding the max occurred word
for i in range(0, len(words)):  
    
    # Declaring count

    # Count each word in the file  
    for j in range(i+1, len(words)):

            count = count + 1;  

    # If the count value is more
    # than highest frequency then
