2024: Week 32 - Pokémon Card Organising

Challenge by: Jenny Martin

I recently got back into Pokémon card collecting, which not only involves collecting new sets, but also going through old sets I had as a child and organising those. For this challenge we'll be focusing on 2 really cool old sets: Gym Heroes and Gym Challenge. They contain cards of Pokémon that belong to particular gym leaders in the Kanto region, such as Blaine's Vulpix, one of my personal favourites:

Now, traditionally, you would organise cards using the number in the bottom right corner e.g. 65/132 in the above example. But for these sets, I wanted to organise them all:
  • based on which gym leader they belong to
  • in the order of the Kanto gyms 
  • with the Gym Leader card first
  • followed by their Gym card
  • followed by the remaining Trainer cards associated with them (in card number order)
  • followed by their Pokémon in Pokédex order
  • using the Pokémon level in the bottom left corner of the card, where a leader has multiple of the same Pokémon
  • with leftover trainer cards not associated with a leader at the end (in card number order, with the Gym Heroes set coming before the Gym Challenge set where there are ties)
You can see why I turned to Tableau Prep to implement this logic! It got quite confusing trying to do it by hand - particularly when I don't own all the cards for these sets. Yet! 

Inputs

We're using a couple of inputs this week. Luckily there's a Pokémon Trading Card Game API that we've pulled most of the data from, as well as using Bulbapedia to get information about the Pokédex number.
  1. Trainer Cards 

  2. Pokémon Cards 

  3. Leader Order 

  4. Pokémon Input 

Requirements

  • Input the data
  • For the Pokémon Cards Input, separate the Gym Leader and Pokémon
    • e.g. Blaine's Vulpix becomes Blaine and Vulpix in separate fields
  • Use the Pokémon Input to bring in information about the Pokédex Number
    • Make sure not to duplicate any rows
  • Combine with the Trainer Cards Input
  • Use the Table Names field to identify the Card Type, either Pokémon or Trainer
  • Any rows that do not have a Leader, assign as "Leftover Trainers"
  • Combine with the Leader Order Input
  • Based on the above description, find a way to sort the cards into the correct order
  • Remove unnecessary fields
  • Output the data

Output


  • 6 fields
    • Sort Order
    • Leader
    • Gym Set
    • Number
    • Card
    • Card Type
  • 252 rows (253 including headers)

Created by: Carl Allchin Welcome to a New Year of Preppin' Data challenges. For anyone new to the challenges then let us give you an overview how the weekly challenge works.  Each Wednesday the Preppin' crew (Jenny, myself or a guest contributor) drop a data set(s) that requires some reshaping and/or cleaning to get it ready for analysis.  You can use any tool or language you want to do the reshaping (we build the challenges in Tableau Prep but love seeing different tools being learnt / tried). Share your solution on LinkedIn, Twitter/X, GitHub or the Tableau Forums Fill out our tracker so you can monitor your progress and involvement The following Tuesday we will post a written solution in Tableau Prep (thanks Tom) and a video walkthrough too (thanks Jenny) As with each January for the last few years, we'll set a number of challenges aimed at beginners. This is a great way to learn a number of fundamental data preparation skills or a chance to learn a new tool — New Year&

 Created by: Carl Allchin Welcome to a New Year of Preppin' Data. These are weekly exercises to help you learn and develop data preparation skills. We publish the challenges on a Wednesday and share a solution the following Tuesday. You can take the challenges whenever you want and we love to see your solutions. With data preparation, there is never just one way to complete the tasks so sharing your solutions will help others learn too. Share on Twitter, LinkedIn, the Tableau Forums or wherever you want to too. Tag Jenny Martin, Tom Prowse or myself or just use the #PreppinData to share your solutions.  The challenges are designed for learning Tableau Prep but we have a broad community who complete the challenges in R, Python, SQL, DBT, EasyMorph and many other tools. We love seeing people learn new tools so feel free to use whatever tools you want to complete the challenges.  A New Year means we start afresh so January's challenges will be focused on beginners. We will use dif

How to...Handle Free Text

Image
Free isn't always a good thing. In data, Free text is the example to state when proving that statements correct. However, lots of benefit can be gained from understanding data that has been entered in Free Text fields. What do we mean by Free Text? Free Text is the string based data that comes from allowing people to type answers in to systems and forms. The resulting data is normally stored within one column, with one answer per cell. As Free Text means the answer could be anything, this is what you get - absolutely anything. From expletives to slang, the words you will find in the data may be a challenge to interpret but the text is the closest way to collect the voice of your customer / employee. The Free Text field is likely to contain long, rambling sentences that can simply be analysed. If you count these fields, you are likely to have one of each entry each. Therefore, simply counting the entries will not provide anything meaningful to your analysis. The value is in
