Yep that's msg.nick. I got so confused by that code for a minute because I thought player *was* msg.nick reading it just now. "Why would msg.nick ever not be msg.nick?!?!"
data = [(data[i-1].lower().capitalize() + ", " + data).split(", ") for i in range(0, len(data), 3)][1:]
That's. some code. that does a thing. Basically it generates lists like ["Bug", "Bug Bite", "Struggle Bug", "Megahorn"].
A piece of text that looks like "Bug Bite, Struggle Bug, Megahorn" is data!
data[i-1] is "BUG". I don't want "BUG" in all caps, so first I do "BUG".lower() to get "bug"! Then I capitalize() it again to get Bug.
"for i in range(0, len(data), 3)" this is a thing that counts by threes! I'll show you.
>>> for i in range(0, 20, 3):
... print i
...
0
3
6
9
12
15
18
See how it counts by threes up to twenty! You can count by twos or fours or anything else, too.
data is all the lines in a text file! http://paste.kde.org/744758/86617741/ This exact text file. So data[0] is "= ATTACK CARDS =", data[1] is an empty line, data[2] is "BUG" and so on.
That [1:] at the end of the code? That copies the whole list from item 1 to the last item. So item zero gets thrown out! It's called a slice when you do that.
>>> list = [0, 1, 2, 3, 4, 5, 6]
>>> print list[1:]
[1, 2, 3, 4, 5, 6]
>>> print list [2:5]
[2, 3, 4]
>>> print list[:4]
[0, 1, 2, 3]
>>>
The reason we're throwing out item zero is that item zero is "= ATTACK CARDS =" and obviously we have no need for that since it's just a title.
So now we can jump on multiples of three (0, 3, 6...) and all of them will be a line like "Struggle Bug, Bug Bite, Megahorn"! So then we can have data. Remember, i in there is a multiple of three.
And we know that the type name (BUG, FIRE, WATER) will always be right above the attacks list! So we can do data[i -1] to get to BUG from "Struggle Bug, Bug Bite, Megahorn". And then we do that capitalizing and lowering thing we talked about already to get "Bug".
And since we have (data[i-1] + ", " + data), we now have... "Bug, Bug Bite, Struggle Bug, Megahorn"!!! (pretend I'm keeping these examples in the same order all the time) Now we can just perform .split(", ") on that.
And ta-dah! We now have ["Bug", "Bug Bite", "Struggle Bug", "Megahorn"].
Why we want that is so I can use csv.writer() to make a csv with the line Bug,Bug Bite,Struggle Bug,Megahorn later. Why we want a csv like that is because it's really easy to read csvs so then I can read it in my TypeFort plugin later.
Here's the whole code:
import csv
with open("attacks.txt") as f:
data = [line.replace("\n", "") for line in f.readlines()]
data = [(data[i-1].lower().capitalize() + ", " + data).split(", ")
for i in range(0, len(data), 3)][1:]
with open("attacks.csv", 'wa') as f:
csv.writer(f).writerows(data)
Since it takes that many paragraphs to explain it (and I messed up on what the .split was doing and had to go back and edit, whoops), it's not a good code. Also, it's a problem if I want to edit the code. More typos can happen, I might forget what a part does and be really confused when my edit doesn't work, etc. It'd be a lot more readable as like...
data = data[1:] #goodbye, "= ATTACK CARDS ="
all_attacks = []
for i in range(0, len(data), 3): #every three
type = data.lower().capitalize() #BUG to Bug
attacks = data[i - 1] #Struggle Bug, Bug Bite, Megahorn
combined = (type + ", " + attacks) #Bug, Struggle Bug, Bug Bite, Megahorn
list = combined.split(", ") #["Bug", "Struggle Bug", "Bug Bite"]
all_attacks.append(list)
That's a little too expanded because we have a bunch of completely pointless variables like combined and list. You need a balance between super-expanded and super-squished. But! It's more readable.
(also you might notice, when you expand things, you can actually leave comments on the lines. There's no space for comments on my squished version.)
Also I just figured out you can do this instead:
>>> "BUG".title()
'Bug'
So that would help the code out a bit.
data = [(data[i-1].lower().capitalize() + ", " + data).split(", ") for i in range(0, len(data), 3)][1:]
vs
data = [(data[i-1].title() + ", " + data).split(", ") for i in range(0, len(data), 3)][1:]
I only get away with writing that super-condensed code because it's a throw-a-way program that I only need for the csv. I have the csv! So I never have to read it again.
I could write it more expanded but I think it's fun to see how condensed I can get code to be. So I practice that when I have baby throw-a-way programs.

But, more importantly, why are you trapped in a list?!?!?!
