Find duplicate words in a string python
|
I can see where you are going with sort, as you can reliably know when you have hit a new word and keep track of counts for each unique word. However, what you really want to do is use a hash (dictionary) to keep track of the counts as dictionary keys are unique. For example: Show Now that will give you a dictionary where the key is the word and the value is the number of times it appears. There are things you can do like using But there is even something better than that... From there you want the list of words in sorted order with their counts so you can print them.

Examples: Input : "Ravi had been saying that he had been there" Output : had Input : "Ravi had been saying that" Output : No Repetition Input : "he had had he" Output : he We have existing solution for this problem please refer Find the first repeated word in a string link. We can solve this problem quickly in python using Dictionary data structure. Approach is simple,
Python3
Output: had Time Complexity: O(length(words)) Auxiliary Space: O(length(dict)) View Discussion Improve Article Save Article View Discussion Improve Article Save Article Given a sentence containing n words/strings. Remove all duplicates words/strings which are similar to each others. Examples: Input : Geeks for Geeks Output : Geeks for Input : Python is great and Java is also great Output : is also Java Python and great We can solve this problem quickly using python Counter() method. Approach is very simple. 1) Split input sentence separated by space into words. Python

Output is Python great and also Java How do I find a repeated word in a string?ALGORITHM. STEP 1: START.. STEP 2: DEFINE String string = "Big black bug bit a big black dog on his big black nose". STEP 3: DEFINE count.. STEP 4: CONVERT string into lower-case.. STEP 5: INITIALIZE words[] to SPLIT the string.. STEP 6: PRINT "Duplicate words in a given string:". STEP 7: SET i=0. ... . STEP 8: SET count =1.. How do I find the most repeated words in a string in python?Use the Counter() function (which gives the frequency of words as a key-value pairs), to calculate the frequency (number of times the word has occurred) of all the words. Create a variable to store the maximum frequency. Loop in the above words frequency dictionary using the for loop.
How do I find a repeated character in a string in python?First, we will find the duplicate characters of a string using the count method.. Initialize a string.. Initialize an empty list.. Loop over the string. Check whether the char frequency is greater than one or not using the count method.. How do I remove repeated words from a string in Python?1) Split input sentence separated by space into words. 2) So to get all those strings together first we will join each string in given list of strings. 3) Now create a dictionary using Counter method having strings as keys and their frequencies as values. 4) Join each words are unique to form single string.
