In this program, we need to print the duplicate elements present in the array.Vst plugins folder windows 10
This can be done through two loops. The first loop will select an element and the second loop will iteration through the array by comparing the selected element with other elements. If a match is found, print the duplicate element. In the above array, the first duplicate will be found at index 4 which is the duplicate of the element 2 present at index 1. So, duplicate elements in the above array are 2, 3 and 8. JavaTpoint offers too many high quality services.

I am looking for a function in Python where you give a string as input where a certain word has been repeated several times until a certain length has reached.
The output would then be that word. The repeated word isn't necessary repeated in its whole and it is also possible that it hasn't been repeated at all. You can do it by repeating the substring a certain number of times and testing if it is equal to the original string.
You'll have to try it for every single possible length of string unless you have that saved as a variable. Loop through it in reverse and stop the first time you find something that's repeated in your string that is, it has a str.
Now if the same substring exists right next to itself, you can return it as the word you're looking for, however you must take into consideration the 'appleappl' example, where the proposed algorithm would return appl. If no such strings are found, you return the whole word since there are no repetitions.

For example, how would it know that 'appleapl' is not a single word? What about words that contain other words?
Find the first repeated word in a string in Python using Dictionary
I'll start with hints. If you're still stuck after trying those, post your attempted solution and we can give you more things to think about and try.We are given a string and we need to remove all duplicates from it? What will be the output if order of character matters? This problem has existing solution please refer Remove all duplicates from a given string.
An OrderedDict is a dictionary that remembers the order of the keys that were inserted first. If a new entry overwrites an existing entry, the original insertion position is left unchanged. This article is contributed by Shashank Mishra Gullu.

Load Comments.In this article, we will discuss how to find duplicates in a list along with their frequency count and their index positions in the list. We have created a function that accepts a list and returns a dictionary of duplicate elements in that list along with their frequency count. When called, this function creates a new dictionary. Then iterates over all the elements in the given list one by one.
For each elements it checks if the element exists in the dictionary keys or not. Once the iteration of list elements ends, in this dictionary we have the frequency count of each element in the list. But as we are interested in duplicates only i. So, it removes the elements from this dictionary whose value is greater than 1. In the end, it returns a dictionary containing duplicate elements as keys and their frequency count as value.
Counter [ iterable-or-mapping ]. We can create an object of Counter class, using an iterable or any dict like mapping. This Counter object keeps the count of each element in iterable. Now we know the frequency count of each duplicate element in the list. But what if we want to know the index position of these duplicate elements in the list?
Now we want to know indices of each duplicate element in list and also their frequency count.The punisher 1994
Something like this. This function accepts a list of items and then iterates over the items in the list one by one to build a dictionary. In this dictionary, the key will be the element but value will be a list of. Your email address will not be published. This site uses Akismet to reduce spam. Learn how your comment data is processed.

Python : How to find keys by value in dictionary?In this program, we need to find out the duplicate words present in the string and display those words.
To find the duplicate words from the string, we first split the string into words. We count the occurrence of each word in the string. If count is greater than 1, it implies that a word has duplicate in the string. JavaTpoint offers too many high quality services. Mail us on hr javatpoint.

In above example, the words highlighted in green are duplicate words. Algorithm Define a string. Convert the string into lowercase to make the comparison insensitive. Split the string into words.
Two loops will be used to find duplicate words. Outer loop will select a word and Initialize variable count to 1. Inner loop will compare the word selected by outer loop with rest of the words. If a match found, then increment the count by 1 and set the duplicates of word to '0' to avoid counting it again.
