How to stop a discord bot from running two or more commands simultaneously - async-await

Question

I'm making a discord bot using discord.py that plays mini-games with a user. The game is working well but while I was debugging it I found out that while the bot is waiting for input from a command and the user enters another command from the same bot, the bot executes the two commands simultaneously. Is there a way to program the bot so that when a command is made and it is currently running a command it should stop the former and execute the latter command without interfering in the games of other users. Just like the way #Pancake is made.
Below is the command for one of the mini-games (Rock, Paper, Scissors).
#bot.command(name="rps", description="Starts a rock, paper, scissors game against the computer")
async def rock_paper_scissors(ctx):
"""Play a game of Rock, Paper, Scissors against the computer"""
print("Game started!") # debug
user_dm = await bot.create_dm(ctx.author)
await user_dm.send("Enter the number of rounds")
def is_int(message):
return message.content.isdigit() and message.channel == user_dm
rounds = await bot.wait_for('message', check=is_int) # get number of rounds input from user
rounds = int(rounds.content)
human = 0
cpu = 0
for _ in range(rounds): # game loop
computer = random.choice(["rock", "scissors", "paper"])
await user_dm.send("Enter rock, paper or scissors")
def is_rps(message):
return message.content.lower() in ['rock', 'paper', 'scissors'] and message.channel == user_dm
player = await bot.wait_for('message', check=is_rps)
player = player.content
await user_dm.send(f"I chose: {computer}")
win = [('R', 'S'), ('P', 'R'), ('S', 'P')]
player, computer = player[0].upper(), computer[0].upper()
if (player, computer) in win:
await user_dm.send("You won! One Point")
human += 1
elif (computer, player) in win:
await user_dm.send("I won! One Point")
cpu += 1
else:
await user_dm.send("Nobody won! No Point")
if human > cpu:
await user_dm.send(f"You won the game! ({human} -> {cpu})")
elif cpu > human:
await user_dm.send(f"I won the game! ({cpu} -> {human})")
else:
await user_dm.send(f"Draw!!! ({cpu} -> {human})")
