命令，没有空格就无法工作，我该如何解决

Question

好吧，我的代码让我很烦，对于我的不和谐机器人来说，如果没有前导空格，它似乎无法工作。

我希望它以两种方式工作，或者只是没有空间，我该怎么做。

这是我的代码：

如何更改我的代码，使其双向工作，或者只是没有空格。

    await ctx.send("Select an amount of time for the giveaway.")
    try:
        since = await client.wait_for('message', check = check, timeout=30.0)

    except asyncio.TimeoutError:
        await ctx.send("You took to long, please try again!")


    seconds = ("s", "sec", "secs", 'second', "seconds")
    minutes= ("m", "min", "mins", "minute", "minutes")
    hours= ("h", "hour", "hours")
    days = ("d", "day", "days")
    rawsince = since.content
    
    
    try:
        time = int(since.content.split(" ")[0])
    except ValueError:
        return await ctx.send("You did not specify a unit of time, please try again.")
        
    since = since.content.split(" ")[1]
    if since.lower() in seconds:
        timewait = time
    elif since.lower() in minutes:
        timewait = time*60
    elif since.lower() in hours:
        timewait = time*3600
    elif since.lower() in days:
        timewait = time*86400
    elif since.lower() in weeks:
        timewait = time*604800
    else:
        
        return await ctx.send("You did not specify a unit of time, please try again.")```

Answer 1

您可以使用正则表达式来提取值：

import re

...

time, unit = re.findall('(\d+) *(.+)', since.content)[0]

Answer 2

try:
    temp = re.compile("([0-9]+)([a-zA-Z]+)")
    res = temp.match(since.content).groups()
    time = int(res[0])
    since = res[1]

This should work!
