Find duplicate words in text file python
This snipped code doesn't use the file, but it's easy to test and study. The main difference is that you must load the file and read per line as you did in your example Show
UPDATE: As suggested by @khachik a better solution is using the Python program to find duplicate words in a file:In this post, we will learn how to find the duplicate words in a file in Python. Python provides different inbuilt methods to work with files. We can use these methods to open a file, read the content of a file and also write content to a file. We will write a program that takes the path of a file as the input and prints out all duplicate words in that file. Before moving to the program, let’s check the algorithm first. Algorithm:This program will follow the below algorithm:
Python program:Let’s write down the program:
Here,
For example, if the input.txt holds the following text:
It will print the below output: Method 2: By using a dictionary:If you run the above program, each time it will print the output in a different order. Because the order is not maintained in a set. If you want to maintain the order, you can use a dictionary. Dictionaries are used to hold key-value pairs. For this example, the key will be the word and the value will be its number of occurrences in the file. The program will iterate through the words and if it is not added to the dictionary, it will add it with value 0. Also, it will increment the value by 1. To find the duplicate words, it will iterate through the dictionary to find out all words with value greater than 1. Below is the complete program:
If you run this program, it will print the duplicate words in the same order these are found in the file. You might also like:

Use the split() function (splits a string into a list. ... . Traverse in the list of words using the for loop.. Use the append() function (adds the element to the list at the end), to append each word to the list.. How do I find the most frequent words in a text file?This can be done by opening a file in read mode using file pointer. Read the file line by line. Split a line at a time and store in an array. Iterate through the array and find the frequency of each word and compare the frequency with maxcount.
