使用不和谐机器人发送多行字符串作为消息时出现布局错误

Question

我启动并运行了一个不和谐机器人。我的目标是在执行某个命令后向用户发送消息。这可行，但不知何故我的布局是错误的。我的字符串的第一行是正确的，之后其余的行将带有一些前导空格发送。

client = commands.Bot(command_prefix = '/')

@client.command()
async def start(ctx):
    welcome_message = f"""
    Welcome to my bot
    here is a new line which has leading spaces
    this line here has some aswell
    """
    await ctx.send(welcome_message)

所以基本上我的消息是这样的：

Welcome to my bot
    here is a new line which has leading spaces
    this line here has some aswell

即使welcome_message = welcome_message.lstrip()在发送之前也不能解决问题。

在这种情况下，缩进是字符串的一部分（因为它是多行字符串），您可以简单地将其删除：

@client.command()
async def start(ctx):
    welcome_message = welcome_message = f"""
Welcome to my bot
here is a new line which has leading spaces
this line here has some aswell
    """
    await ctx.send(welcome_message)

如果您想保留缩进，请使用以下textwrap.dedent方法：

import textwrap

@client.command()
async def start(ctx):
    welcome_message = welcome_message = f"""
    Welcome to my bot
    here is a new line which has leading spaces
    this line here has some aswell
    """
    await ctx.send(textwrap.dedent(welcome_message))
