Discord Python 机器人的嵌入

Question

所以我制作了这段代码，用户可以在其中选择自己的嵌入颜色，但如果他们嵌入错误的内容，它会搞砸整个事情，他们需要重做，如果他们不这样做，有没有办法做到这一点？ t 响应或输入不正确的十六进制代码，它将自动转到十六进制颜色 FF00EC。

@client.command(aliases=['say'])
@commands.has_permissions(manage_messages=True)
async def embed(ctx):

    questions = ["Which should be the tile of the embed?",
            "What should be the description?",
            "What is the color of the embed? This should be a hex color. Note, Must put a `Correct` Hex color or you will need to redo this also leave out the #."]

    answers = []

    def check(m):
        return m.author == ctx.author and m.channel == ctx.channel

    for i in questions:
        await ctx.send(i)

        try:
            msg = await client.wait_for('message', timeout=30, check=check)
        except asyncio.TimeoutError:
            await ctx.send('You did not answer in time. Please do it under 30 seconds next time.')
            return
        else:
            answers.append(msg.content)

    embedcolor = answers[2]

    embed = discord.Embed(description=answers[1], title=answers[0], colour=int(embedcolor, 16))

    await ctx.send(embed=embed)

这是我的代码

您可以使用 try except 语句轻松完成此操作。

import re
@client.command(aliases=['say'])
@commands.has_permissions(manage_messages=True)
async def embed(ctx):

    questions = ["Which should be the tile of the embed?",
            "What should be the description?",
            "What is the color of the embed? This should be a hex color. Note, Must put a `Correct` Hex color or you will need to redo this also leave out the #."]

    answers = []

    def check(m):
        return m.author == ctx.author and m.channel == ctx.channel

    for i in questions:
        await ctx.send(i)

        try:
            msg = await client.wait_for('message', timeout=30, check=check)
        except asyncio.TimeoutError:
            await ctx.send('You did not answer in time. Please do it under 30 seconds next time.')
            return
        else:
            answers.append(msg.content)

    embedcolor = answers[2]

    embed = discord.Embed(description=answers[1], title=answers[0], colour=int(embedcolor, 16))
    if re.search(r'^#(?:[0-9a-fA-F]{3}){1,2}$', embedcolor):
        await ctx.send(embed=embed)
    else:
        embed = discord.Embed(description=answers[1], title=answers[0], colour=int("FF00EC", 16))
        await ctx.send(embed=embed)

基本上，如果颜色无效，我们将颜色设置为 FF00EC 并像这样发送消息。
