python - DIScord 命令认为 bool 为 True

Question

我有 3 个命令。 !disablepugs、!enablepugs 和 !join。 !disablepugs 将变量设置为 False，而 !enablepugs 将变量设置为 true。但是，变量更改得很好。但是，当我在 !join 命令中检查变量是否等于 True 时，它​​仍然没有检测到变化。代码:

#Set default to True, shouldn't matter too much
pugs_enabled = True

@client.command()
async def disablepugs(ctx):
    user = ctx.message.author.name

    if user == "*My Name Here*":
        pugs_enabled = False
        await ctx.send("``Pugs are temporarily disabled.``")
        print(f"Set to {pugs_enabled}")

@client.command()
async def enablepugs(ctx):
    user = ctx.message.author.name

    if user == "*My Name Here*":
        pugs_enabled = True
        await ctx.send("``Pugs are now enabled.``")
        print(f"Set to {pugs_enabled}")

@client.command()
async def join(ctx):
    if helper.is_setup(ctx):
        print(f"The pug variable is set to {pugs_enabled}")
        if pugs_enabled is True:
            #Not detecting bool change. Still thinks it's false

关于为什么的任何想法？我难住了...

pugs_enabled是一个全局变量。您可以从任何范围访问全局变量，但是每当您尝试更改它们的值时，您都会创建一个具有相同名称的局部变量，并且只修改该局部变量。您必须显式地将全局变量“ Hook ”到您的作用域中以修改全局值。

pugs_enabled = True

@client.command()
async def disablepugs(ctx):
    user = ctx.message.author.name

    if user == "*My Name Here*":
        global pugs_enabled
        pugs_enabled = False
        await ctx.send("``Pugs are temporarily disabled.``")
        print(f"Set to {pugs_enabled}")

@client.command()
async def enablepugs(ctx):
    user = ctx.message.author.name

    if user == "*My Name Here*":
        global pugs_enabled
        pugs_enabled = True
        await ctx.send("``Pugs are now enabled.``")
        print(f"Set to {pugs_enabled}")

@client.command()
async def join(ctx):
    if helper.is_setup(ctx):
        print(f"The pug variable is set to {pugs_enabled}")
        if pugs_enabled is True:
            #Not detecting bool change. Still thinks it's false
