我找不到我的不和谐机器人中的错误

Question

我正在制作一个正在更改行会频道名称的机器人。但是，当我使用node.js运行程序时，我的函数返回了未定义的值，这是一个问题。但是在功能上一切都是真的。

   function fetchdataFromApiUsd(moneykind){
    fetch("https://api.exchangeratesapi.io/latest?base="+moneykind)
    .then((resp) => resp.json())
    .then((data) =>{
        const sonuc = data.rates
        console.log(sonuc.TRY);//The values come true.
        return sonuc.TRY;
       
    } )
    .catch(err => console.log(err));
   }

但是当我这样打电话

   client.on('message', msg => {
     if (msg.content === 'ping') {
      msg.reply('Pong!');
       }
     if(msg.content==='hiThere'){
       const currentusd=fetchdataFromApiUsd("USD");
       const currenteuro=fetchdataFromApiUsd("EUR");
      let myGuild = client.guilds.cache.get(msg.guild.id)
      let channel = myGuild.channels.cache.get('297798780592324610')
      let channel1 = myGuild.channels.cache.get('297798809533022208')
      channel.setName('1 Dolar = '+currentusd) //Returns undefined
      channel1.setName('1 Euro = '+currenteuro)//Returns undefined
     .catch()
     console.log(currentusd)  //Returns undefined
     console.log(currenteuro) //Returns undefined
  }
});

我的错误是异步变量。我用大括号定义变量。好了另外，您应该在函数中调用这些变量以再次定义更新值。

min_value = None
max_value = None

for i in range(number_of_stats):

    stat_score = int(input('Please enter the stats #%s:  ' % (i+1)))

    stat_sum += stat_score
    if min_value is None or stat_score < min_value:
        min_value = stat_score
    if max_value is None or stat_score > max_value:
        max_value = stat_score
