Python Program to Find the Most Repeated Word in a Text File

Given a text file, the task is to find the most repeated word in the given text file in Python.

Program to Find the Most Repeated Word in a Text File

Approach:

import the Counter from the collections module using the import keyword.
Make a single variable to store the path of the file. This is a constant value. This value must be replaced with the file path from your own system in the example below.
Take an empty list to store all the words.
Open the file in read-only mode. In this case, we’re simply reading the contents of the file.
Iterate through the lines of the file using the For loop.
Split the words of the line using the split() function and store them in a variable(it is of type list).
Loop in the above list using another Nested For loop.
Add the words to the list using the append() function.
Get the frequency of all the words using the Counter() function and store it in a variable(of type dictionary).
Take a variable to store maximum frequency and initialize its value to 0.
Traverse in the frequency dictionary using the For loop
Check if the frequency of the word is greater than maximumfreq using the if conditional statement
If it is true then set maximumfreq to the corresponding value of the key.
Take a variable to store the maximum frequency key.
Print the maximum frequency element.

Below is the implementation:

# import the Counter from collections module using the import keyword
from collections import Counter
# Make a single variable to store the path of the file. This is a constant value.
# This value must be replaced with the file path from your own system in the example below.
givenFilename = "samplefile.txt"
# Take a empty list to store all the words
l = []
# Open the file in read-only mode. In this case, we're simply reading the contents of the file.
with open(givenFilename, 'r') as givenfilecontent:
    # Iterate through the lines of the file using the For loop.
    print('The words in the given file : ')
    for gvnfileline in givenfilecontent:
      # Split the words of the line using the split() function and store them in a variable(it is of type list).
        gvnfilewords = gvnfileline.split()
        # Loop in the above list using another Nested For loop
        for words in gvnfilewords:
          # Add the words to the list using the append() function.
            l.append(words)
# Get frequency of all the words using the Counter() function and store it in a variable(of type dictionary)
freqword = Counter(l)
# Take a variable to store maximum frequency
maximumfreq = 0
# Traverse in the frequency dictionary using the For loop
for i in freqword:
    # Check if the frequency of the word is greater than maximumfreq using the if conditional statement
    if(freqword[i] > maximumfreq):
        # If it is true then set maximumfreq to the corresponding value of the key
        maximumfreq = freqword[i]
        # Take a variable to store the maximum frequency key
        maxele = i
# Print the maximum frequency element
print('The Maximum Frequency element in the given Text File {', maxele, '}')

Output:

The words in the given file : 
The Maximum Frequency element in the given Text File { btechgeeks }

Explanation:

The file path is stored in the variable ‘file name.’ Change the value of this variable to the path of your own file.
Dragging and dropping a file onto the terminal will show its path. The code will not run unless you change the value of this variable.
The file will be opened in reading mode. Use the open() function to open a file. The path to the file is the method’s first parameter, and the mode to open the file is the method’s second parameter.
When we open the file, we use the character ‘r’ to signify read-mode.
The split() method separates all of the words in the given file.
We add all the words to the list.
We apply the Counter() function to get the frequency of all the words of the given text file.

Samplefile.txt:

hello this is btechgeeks
hello good morning 
this is btechgeeks
btechgeeks btechgeeks
