Binding variable in loop changes it's type

I'm trying to make some order in a script that uses nicegui. I'm using a dictionary to store all button labels and the pages they will redirect to.

I'm iterating over all keys in pages dictionary and calling ui.button for each of them.

from nicegui import ui

pages = {'page_one':'Page','page_two':'Page 2','page_three':'Page 3'}

for page in pages:
    ui.button(pages[page], on_click=lambda page: ui.open(page))

when binding page it becomes a completely different type nicegui.events.ClickEventArguments instead of a normal string

not binding page causes all buttons to redirect to page_three

ui.button(pages[page], on_click=lambda: ui.open(page))

I feel like I completely misunderstand what actually binding is and how lambdas operate.

Why is the page variable changing type when bound to function in this context?

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 ...
