An algorithm to set text in files to arrays



This post took a little too long to get out. It has been a busy week. Every class I had required me to either write an essay or take a test. I have also started to do some multiplayer HOI4 games with friends.Thus I did not have time to write up this post. At least it is still less than two weeks since the last post. Regardless, here is something I have made that was not a computer science project.

With my work in the prior post about prime factorization, I used some of Python's functions to get a list of prime numbers from a text file. This led me to try some things further with the reading/writing functions.

This is a simple function that takes lines from a text file and puts them into lists. You can find it here on Github. The following is the basic steps:
  1. Check to see what tag is the current line. The line with a tag is indicated by it starting with a hashtag
  2. Add all lines to the list related to that tag until the current line is a tag
  3.  Check to see what tag is the current line again. Check again if it wasn't found the first time.
  4. If no tag was found while checking twice, stop checking.
  5. If the current line is #End, close the file. 
I attempted to abstract the tag checking to the point it could be its own function, but I could not find a workable version. Thus, in order to use it, one will have to prior add the tags into the code by copying and pasting the whole pieces needed. Thankfully the need lines are all together,

As I felt a little wrong being late, I decided to add a little more to the code. I've also added a simple function where I could write in the lines of the file until I put in #End.

The example used for this was the sorting of greetings and goodbyes. I would enter in the tag #Greetings, followed by various greetings one at a time. Next, I would enter in the tag #Goodbyes, followed by various goodbyes one at a time. The algorithm will look for the tags, and put them into their respective list. The algorithm will work even if you switch the order.

This was simply a test of file handling in Python. My next post may possibly be a look back at the idle game I made prior. Until then, see you next time.

Version 2:The Not-So Barebones Clicker

Image
I was originally going to make this post tomorrow, but due to events I am doing it today when I can. As seen, I have updated the Barebones Clicker to become a Not-So Barebones Clicker. This is now more than just a button and a counter. As you can see, one of the big changes was generators. There are currently three of them. These are not really made to be fair though, as I'm pretty sure some are way more efficiant than others, but I wasn't really concerned with that.An interesting part about the generators is that if you try to buy them and you don't got the money, a message will appear for a few seconds telling you that you can't afford it. Another big change included was the save. This is not a good save, as it just relies on cookies. Yet, you can refesh the page, and the numbers will still be there (given that one saves and loads). This took hours to code, specifically to make functional. I went to Dhmstark again along with stackexchange for coding help. S

A Prime Factorization Algorithm that Uses a Text File

Image
A post that is at least within two week of the last one? This will hopefully be the new norm. I was about to get this out two days prior, but Github had some issues when I was about to upload it on the first day. I got this uploaded to Github the yesterday, but it was late, so I didn't make a post. Nevertheless, it's time to talk about this code. I have created a python program that shall do prime factorization when given an integer. You can find it here on Github .  The Background So this is another program requested by my computer science teacher. He demanded a program that would be given a number and return the prime factors of it along with how many times each was used (and specifically in the order you see in the program's output). Initially, I though this was an easy program. There's a rule I've known since middle school on how to prime factorize: Start by dividing the number by 2 for as many times possible When you can no longer divide by 2, div

Aesthetico Ultimate Designer - A Python Turtle Program

Image
In the last post on my previous work, I tried to use a program I made in my Python class. It used the Turtle module to make lines. However, it seems that I forgot to save the code for that (and I didn't have a Repl account back then). So I just put something else up instead.  Over December, I've tried to remake that program I once made before on REPL . This is the best thing I could recreate, since I did not have anything to build upon other than the memory of it.  It's a simple program. It will ask which direction and degree the line should turn to. It then asks what type of line to make, and then it creates the line. You can continue on and create more lines, or simply end it.  I tried to keep up this somewhat professional and Aesthetic look back when I first made it long ago. I used colours from an Aesthetic colour pallet, and I had every word between dashes. I will say, it somewhat looks cool.   I will say, however, that this remake is not as good a
