Is there a way to make the "global" command carry into and through a discord.py command?

Question

global t
t = 0
@bot.command()
async def ping(ctx, member: discord.Member):
  while True:
    await ctx.channel.send(member.mention)
    @bot.event
    async def on_message(message):
      try:
        if message.author == member:
          t = 5     #(A)
          return
      except:
        pass
    if t == 5:
      break

Line (A) shows an error. I assumed the problem was that the variable t was not carrying through the @bot.event, but it seems like even the global command does not work. Is there some other problem that I just don't see?

Explanation

When defining t, you are already defining it at the module (global) level. Thus, the global t command is redundant.

Instead, you should use global inside each new local scope you want to use t in.

As of now, the statement t = 5 creates a variable local to on_message. You probably want to edit the global t, which can be accomplished with the following edits to your code:

Code

t = 0
@bot.command()
async def ping(ctx, member: discord.Member):
  while True:
    await ctx.channel.send(member.mention)
    @bot.event
    async def on_message(message):
      global t  # Since we are assigning t in this function, we must state to use t from the global scope
      try:
        if message.author == member:
          t = 5     #(A)
          return
      except:
        pass
    if t == 5:
      break
