Stuck using pandas to build RPG item generator - python-3.x

Question

I am trying to build a simple random item generator for a game I am working on.
So far I am stuck trying to figure out how to store and access all of the data. I went with pandas using .csv files to store the data sets.
I want to add weighted probabilities to what items are generated so I tried to read the csv files and compile each list into a new set.
I got the program to pick a random set but got stuck when trying to pull a random row from that set.
I am getting an error when I use .sample() to pull the item row which makes me think I don't understand how pandas works. I think I need to be creating new lists so I can later index and access the various statistics of the items once one is selected.
Once I pull the item I was intending on adding effects that would change the damage and armor and such displayed. So I was thinking of having the new item be its own list then use damage = item[2] + 3 or whatever I need
error is: AttributeError: 'list' object has no attribute 'sample'
Can anyone help with this problem? Maybe there is a better way to set up the data?
here is my code so far:
import pandas as pd
import random
df = [pd.read_csv('weapons.csv'), pd.read_csv('armor.csv'), pd.read_csv('aether_infused.csv')]
def get_item():
item_class = [random.choices(df, weights=(45,40,15), k=1)] #this part seemed to work. When I printed item_class it printed one of the entire lists at the correct odds
item = item_class.sample()
print (item) #to see if the program is working
get_item()

I think you are getting slightly confused with lists vs list elements. This should work. I stubbed your dfs with simple ones
import pandas as pd
import random
# Actual data. Comment it out if you do not have the csv files
df = [pd.read_csv('weapons.csv'), pd.read_csv('armor.csv'), pd.read_csv('aether_infused.csv')]
# My stubs -- uncomment and use this instead of the line above if you want to run this specific example
# df = [pd.DataFrame({'weapons' : ['w1','w2']}), pd.DataFrame({'armor' : ['a1','a2', 'a3']}), pd.DataFrame({'aether' : ['e1','e2', 'e3', 'e4']})]
def get_item():
# I removed [] from the line below -- choices() already returns a list of length 1
item_class = random.choices(df, weights=(45,40,15), k=1)
# I added [0] to choose the first element of item_class which is a list of length 1 from the line above
item = item_class[0].sample()
print (item) #to see if the program is working
get_item()
prints random rows from random dataframes that I setup such as
weapons
1 w2
