Trying to ask user confirmation for discord.py bot command, but doing so neglects the "if and elif block" entirely - discord

Question

I have imported everything needed for the command.
So, the issue here is, in the condition for executing the command (checking if the user said yes/no or something weird which terminates the command)
#commands.command()
#commands.has_permissions(manage_channels=True)
async def nuke(self, ctx,*, channel = None, reason = None):
if reason is None:
reason = "No reason was specified!"
if channel is None:
channel = ctx.channel
p = time.strftime(f'Today at %H:%M %p')
embei = discord.Embed(color=0xa3a3ff, title = ":warning: ALERT ALERT ALERT :warning: ", description=f"{ctx.author.mention} Are you sure you want to delete {ctx.channel.mention}? y/n")
await ctx.send(embed=embei)
msg = await self.client.wait_for('message', check=lambda message:message.author == ctx.author and message.channel.id == ctx.channel.id)
if msg.content.lower in ("y", "yes"):
embedis = discord.Embed(color=0xa3a3ff, title=f"Channel ({ctx.channel.name}) has been nuked :boom:", description=f"Nuked by: {ctx.author.name}#{ctx.author.discriminator} \n **Reason:** {reason}")
embedis.set_image(url = "https://66.media.tumblr.com/23dad7011515a9c21647fefb07e1c0e0/dd0cbd9bb94e2a45-1e/s640x960/a02fc34abff6953c59adafc190de6e5276969175.gif")
embedis.set_footer(text=f"Rylie - Thanks for using this bot! - {p} - {self.client.version}", icon_url = str(self.client.user.avatar_url))
await ctx.channel.delete(reason=reason)
channel = await ctx.channel.clone()
await channel.send(embed=embedis)
elif msg.content.lower in ("n", "no"):
embegs = discord.Embed(color=0xa3a3ff, title = ":red_circle: NOTICE :red_circle:", description = f"{ctx.channel.mention} was not nuked!")
embegs.set_footer(text=f"Rylie - Thanks for using this bot! - {p} - {self.client.version}", icon_url = str(self.client.user.avatar_url))
await ctx.send(embed=embegs)
else:
embers = discord.Embed(color=0xa3a3ff, title = ":red_circle: NOTICE :red_circle:", description = "No proper response was given, action was terminated")
embers.set_footer(text=f"Rylie - Thanks for using this bot! - {p} - {self.client.version}", icon_url = str(self.client.user.avatar_url))
await ctx.send(embed=embers)
The part with the issue
msg = await self.client.wait_for('message', check=lambda message:message.author == ctx.author and message.channel.id == ctx.channel.id)
if msg.content.lower in ("y", "yes"):
embedis = discord.Embed(color=0xa3a3ff, title=f"Channel ({ctx.channel.name}) has been nuked :boom:", description=f"Nuked by: {ctx.author.name}#{ctx.author.discriminator} \n **Reason:** {reason}")
embedis.set_image(url = "https://66.media.tumblr.com/23dad7011515a9c21647fefb07e1c0e0/dd0cbd9bb94e2a45-1e/s640x960/a02fc34abff6953c59adafc190de6e5276969175.gif")
embedis.set_footer(text=f"Rylie - Thanks for using this bot! - {p} - {self.client.version}", icon_url = str(self.client.user.avatar_url))
await ctx.channel.delete(reason=reason)
channel = await ctx.channel.clone()
await channel.send(embed=embedis)
elif msg.content.lower in ("n", "no"):
embegs = discord.Embed(color=0xa3a3ff, title = ":red_circle: NOTICE :red_circle:", description = f"{ctx.channel.mention} was not nuked!")
embegs.set_footer(text=f"Rylie - Thanks for using this bot! - {p} - {self.client.version}", icon_url = str(self.client.user.avatar_url))
await ctx.send(embed=embegs)
else:
embers = discord.Embed(color=0xa3a3ff, title = ":red_circle: NOTICE :red_circle:", description = "No proper response was given, action was terminated")
embers.set_footer(text=f"Rylie - Thanks for using this bot! - {p} - {self.client.version}", icon_url = str(self.client.user.avatar_url))
await ctx.send(embed=embers)
when I execute the command, it does ask me for the confirmation as expected, however, the reply here doesn't matter as it always executes the else statement. I thought the issue was with indentation and so I tried fixing that but that too didn't work. Does anyone know about the issue here I might be facing?
Extra: Before Adding user confirmation, the code was working absolutely fine! (It created a clone of the channel, sent the embed there saying it nuked the original channel, and deleted the original channel)

Answer 1

For this question of mine, the string.lower() is a method which I need to call, which was mentioned to me by Lukasz. I was using the string.lower() in the wrong way.
To Fix the problem I had, I declared two lists a and b
a=["y", "yes"]
b = ["n", "no"]
and changed
if msg.content.lower in ("y", "yes"):
elif msg.content.lower in ("n", "no"):
to
if msg.content in a:
elif msg.content in b:
and the issue was fixed.
