【问题描述】：

设置现有角色的颜色？

这是我创建角色的代码：

roles = ["SSS | Weeb", "SS Rang | Weeb", "S Rang | Weeb", "A Rang | Weeb", "B Rang | Weeb",
                 "C Rang | Weeb", "D Rang | Weeb", "E Rang | Weeb", "F Rang | Weeb", "Junior Rang | Weeb"]
        for i in roles:
            seasons = discord.utils.get(message.guild.roles, name=str(i))
            if str(seasons) == str(i):
                pass
            else:
                await message.guild.create_role(name=str(i))

现在我想在那里设置类似的东西

roles = ["SSS | Weeb", "SS Rang | Weeb", "S Rang | Weeb", "A Rang | Weeb", "B Rang | Weeb",
                 "C Rang | Weeb", "D Rang | Weeb", "E Rang | Weeb", "F Rang | Weeb", "Junior Rang | Weeb"]
        colors = ["red, green", "blue"] # and much more
        for i in range(len(roles)):
            seasons = discord.utils.get(message.guild.roles, name=str(roles[i]))
            if str(seasons) == str(roles[i]):
                pass
            else:
                await message.guild.create_role(name=str(roles[i]))
            ->  await message.guild.add_color_to_role(role_name=str(roles[i]), color=colors[i])

我什么都没找到……

【解决方案1】：

没有Guild.add_color_to_role这样的东西，它是Role.edit并将颜色作为kwargs传递，你也可以在创建角色时传递颜色：

# Editing the role
await role.edit(colour=discord.Colour.blue())
# Creating a role with the color
await guild.create_role(name="whatever", colour=discord.Colour.blue())

您还可以将十六进制值传递给颜色 kwarg

await guild.create_role(name="whatever", colour=0xff0000) # Red color

因此，您的颜色列表必须是 discord.Colour 实例列表或整数列表

colors = [0xff0000, discord.Colour.blue(), 0x00ff00]

要同时浏览两个列表，您可以使用zip 函数（注意：两个列表的长度应该相同）

role_names = ["name1", "name2", "name3"]
role_colors = [0xff0000, 0x00ff00, 0x0000ff] 

for name, color in zip(role_names, role_colors):
    print(f"Name: {name}, color: {color}")

# Name: name1, color: 0xff0000
# Name: name2, color: 0x00ff00
# ...

你的代码看起来像这样

role_names = ["name1", "name2", "name3"]
role_colors = [0xff0000, 0x00ff00, 0x0000ff] # The default color is 0x000000 (white)

for name, color in zip(role_names, role_colors):
    print(f"Name: {name}, color: {color}") # -> Name: name1, color: 0xff0000 ...

    # Getting the role
    role = discord.utils.get(message.guild.roles, name=name)
    # Checking if the role exists (in other words - if the `role` variable is not a NoneType)
    if role is not None: 
        # Role does not exist, create it here
        role = await message.guild.create_role(name=name, colour=color)

编辑

使用像#5482a5这样的颜色

color = "#5482a5"
color = color[1:] # removing the initial `#`
color = int(color, 16) # pass this as the colour kwarg

参考：

非常感谢 :) 我也可以使用这种格式的颜色吗：#5482a5 ？
是的！但是您必须将它们转换为以 16 为底的整数，让我编辑答案
太感谢你了 :)
通过转换颜色得到这个错误：ValueError: invalid literal for int() with base 16: '#b1afc8'
color = colors[i] color = color[1:] # removing the initial #` color = int(color, 16) # 将此作为颜色 kwarg 传递`

【解决方案2】：

您可以在创建角色时指定颜色。

await message.guild.create_role(name=str(roles[i], colour=discord.Color.blue()))

既然您实际上询问了如何编辑颜色，您可以这样做：

role = await message.guild.create_role(name=str(roles[i]))
await role.edit(colour = discord.Colour.orange())
