remove-duplicate | A simple script to remove duplicate words in wordlists | Generator Utils library

I am aware this is an almost duplicate of this solution

However I am not able to work out why for my example (similar to a real data issue) why it is not fully removing the duplicates.

the code I am using removes 2 of the 4 and not 3?

I am attempting to create a python script that cleans duplicates from xml files.

code;

I have an array like this:

I have searched for a solution for how to remove duplicates from a list with Stream API

found only this question How to remove duplicates from list of objects by id

I have a list of Person i need to filter by the person name, tried with the below snippet but it doesn't filter by the name

I need to merge several files, removing redundant lines among files, while keeping redundant lines within files. A schematic representation of my files is the following:

How can I perform the following operations on a pandas dataframe?

1. combine text from one column, multiple rows into one row
2. remove duplicates in the "one row"
3. repeat 1 & 2 for multiple columns

Based on the following Stack Overflow questions and answers, I have made the attempted code below. The last attempt is close, but I do not know how to convert the set back into a string (i.e., remove the braces) and roll it into a lambda function that I can use applymap() for multiple columns.

1. How to combine multiple rows into a single row with pandas [duplicate]
2. Concatenate strings from several rows using Pandas groupby
3. Remove duplicates from rows and columns (cell) in a dataframe, python

Example Dataframe

Let's say I try to insert some json data in my column like this:

[{"key": "a", "value": 1}, {"key":"a", "value": 20}]

The same key-value object could occur multiple times in the array. But there is only one array in the column.

I would like to have it so that only the first occurence of the same key gets entered into the database, in this array.

So the end result would be

[{"key": "a", "value": 1}]

Either that or after inserting a separate SQL update statement to filter out all the duplicates. Is that possible with Mysql 5.7, or 8?

My situation is similar to this question, but for MYSQL

Before you mark this question as duplicate of this please read the whole thing:

I have a table in Lua which is a table of tables something like the below one and I want to remove all the duplicate tables in it.

When loading .gdbinit, gdb prints out the config lines with a "+" prefix, as well as echos any command I type with a "+" prefix. How do I stop it from printing these lines? See an example below.

This becomes an issue when I use editor integration - specifically tried with emacs - where it calls "info break" in the background. It is printed on the console as "+info break" in a continuous stream, making the gdb prompt unusable.

I've been struggling to understand linked lists, and have read so many (tutorials/articles etc) about them, but cant quite grasp it. I am trying to solve a leetcode problem here. Here is the problem statement:

Given the head of a sorted linked list, delete all duplicates such that each element appears only once. Return the linked list sorted as well.

In the particular sample solution below, is var current just a reference to the node/nodes in head?
