Unnamed: 0" column impossible to erase

Hello I have a code that filters some rows of a csv and creates a csv without those rows but when I create that csv I get a column called "Unnamed: 0" and it is impossible to delete it.

import pandas as pd

df = pd.read_csv("table.csv")
df.drop(df[df['Stock'].eq('No')].index, inplace=True)
df.to_csv('pedro.csv', index=False )

I have tried everything, I have even set index = False but it still comes out.

And I have also tried using drop

import pandas as pd

df2= pd.read_csv("pedro.csv")
df2.drop("Unnamed: 0", axis=1)

But it still doesn't work because it returns this:

   Unnamed: 0                                  Titulo        Precio Stock Ultima Vez
0           0  RPi CM4 - 8GB RAM, 32GB MMC, With Wifi  (EUR) 120.52   Yes  20-Nov-22

Confusion between commands.Bot and discord.Client | Which one should I use?

Whenever you look at YouTube tutorials or code from this website there is a real variation. Some developers use client = discord.Client(intents=intents) while the others use bot = commands.Bot(command_prefix="something", intents=intents) . Now I know slightly about the difference but I get errors from different places from my code when I use either of them and its confusing. Especially since there has a few changes over the years in discord.py it is hard to find the real difference. I tried sticking to discord.Client then I found that there are more features in commands.Bot . Then I found errors when using commands.Bot . An example of this is: When I try to use commands.Bot client = commands.Bot(command_prefix=">",intents=intents) async def load(): for filename in os.listdir("./Cogs"): if filename.endswith(".py"): client.load_extension(f"Cogs.{filename[:-3]}") The above doesnt giveany response from my Cogs ...
