How do I get the most recent call of a command, and save it in a function? [closed]

I’ve been messing with bots for a couple days now, and I’m trying to get the name of the user that called a certain command, then be able to use that later on in a different command. I’ve tried using context.author, as in the example below, but it doesn’t seem to work.

client = commands.Bot(command_prefix="!")

@client.command()
async def help(ctx):
    await ctx.send("Test string")
    variable = context.user  
    #variable is updated each time help function is called

@client.command()
async def get_user(ctx):
    await ctx.send(variable)

Answer

You can just use a global variable.

variable = ""

@client.command()
async def help(ctx):
    global variable
    await ctx.send("Test string")
    variable = str(ctx.author.name)

@client.command()
async def get_user(ctx):
    global variable
    await ctx.send(variable)
