Discord.py error: "ValueError: <class 'str'> is not a valid ChannelType" - discord.py

Question

I don't understand what the error is.

Code:

async def weather(ctx, *, city: str):
city_name = city
complete_url = base_url + "appid=" + api_key + "&q=" + city_name
response = requests.get(complete_url)
x = response.json()
channel = ctx.message
if x["cod"] != "404":
async with discord.channel.ChannelType(value=str):

current_temperature = y["температура"]
current_temperature_celsiuis =str(round(current_temperature - 273.15))
current_pressure = y["давление"]
current_humidity = y["влажность"]
z = x["погода"]
weather_description = z[0]["описание"]
weather_description = z[0]["описание"]
embed = discord.Embed(title=f"Погода в {city_name}",
color=ctx.guild.me.top_role.color,
timestamp=ctx.message.created_at,)
embed.add_field(name="Описание", value=f"**{weather_description}**", inline=False)
embed.add_field(name="Температура(C)", value=f"**{current_temperature_celsiuis}°C**", inline=False)
embed.add_field(name="Влажность(%)", value=f"**{current_humidity}%**", inline=False)
embed.add_field(name="Atmospheric Pressure(hPa)", value=f"**{current_pressure}hPa**", inline=False)
embed.set_thumbnail(url="https://i.ibb.co/CMrsxdX/weather.png")
embed.set_footer(text=f"Запрошенный {ctx.author.name}")
await channel.send(embed=embed)
else:
await channel.send("Город не найден.")
I tried to change a lot of things, but I still can't figure out what the problem is.

Answer 1

There's a few issues with your code - that error is probably just the first one. I've attempted to rewrite what you've provided with some explanation but hopefully it replicates what you're trying to do.
#bot.slash_command(name="weather", description="Погода")
async def weather(ctx, *, city: str):
# as we're doing an API call here - let's defer so the interaction doesn't timeout
await ctx.defer()
# no reason to redefine another variable called 'city_name' equal to 'city' - just use 'city' everywhere
# could also use a f-string for creating the URL here
# complete_url = f"{base_url}appid={api_key}&q={city}"
complete_url = base_url + "appid=" + api_key + "&q=" + city
response = requests.get(complete_url)
json_response = response.json()
if json_response["cod"] == "404":
# if it's 404, let's send the error message and return early
# means we don't have a big nested "if" block
await channel.send("Город не найден.")
return
y = json_response["главный"]
z = json_response["погода"]
current_temperature = y["температура"]
current_temperature_celsiuis =str(round(current_temperature - 273.15))
current_pressure = y["давление"]
current_humidity = y["влажность"]
weather_description = z[0]["описание"]
weather_description = z[0]["описание"]
# create the embed
embed = discord.Embed(
title=f"Погода в {city}",
color=ctx.guild.me.top_role.color,
timestamp=ctx.message.created_at
)
embed.add_field(name="Описание", value=f"**{weather_description}**", inline=False)
embed.add_field(name="Температура(C)", value=f"**{current_temperature_celsiuis}°C**", inline=False)
embed.add_field(name="Влажность(%)", value=f"**{current_humidity}%**", inline=False)
embed.add_field(name="Atmospheric Pressure(hPa)", value=f"**{current_pressure}hPa**", inline=False)
embed.set_thumbnail(url="https://i.ibb.co/CMrsxdX/weather.png")
embed.set_footer(text=f"Запрошенный {ctx.author.name}")
# now let's send our response
# ctx.send will send to the channel that the user used the slash command in
await ctx.send(embed=embed)
The ctx variable docs.
What I changed:
removed creating a variable called city_name that was exactly equal to city - seemed redundant
added ctx.defer() - if our code takes a little while it's good to defer so the interaction doesn't timeout
removed channel = ctx.message. We can get the channel later if we need to (we don't in this case) but this was setting it equal to the message that invoked the application command (which isn't really a message) so we aren't accomplishing anything here anyways
if we get a 404 response; send error message and return. Better to do this than have a big nested if block in my opinion.
I also renamed x to json_response as I prefer descriptive variable names but I gave up on y and z.
got rid of the whatever the async with statement was trying to accomplish
used ctx.send(embed=embed) at the bottom to send your created embed to the channel that the user used the application command in
Hopefully, this is what you want it to do and hopefully you understand what's going on a bit now. It might be worth having a look through some of the examples and documentation to get a better grasp on how it all works.
Another change you could make, is swapping out requests for aiohttp-requests to make non-blocking API calls.

Answer 2

I took advantage of your help, and I am grateful to you in many ways, but I am just starting my way in programming and learning from a real example. So I corrected my code to yours and I was given a new set of errors, which I also can't figure out a little.
