print(get_prices())大家好，我对python编程还不太在行。我大约一年前开始工作，在封锁期间停了下来。现在回到正题，并决定为加密货币构建一个价格机器人。我想从这个网站上提取数据："https://api.pancakeswap.info/api/tokens“，并将这些数据保存在"priceusd”和"pricebnb“中。
我希望我已经解释得足够好了。
我想从网站上提取数据，但是我使用的代码似乎不起作用。它每次都会给我一个“原始”错误。
我们将非常感谢所有的帮助。谢谢!

你只是用错了钥匙。

for i in crypto_data:

"coin": i,
"priceusd": crypto_data[i]["price"],
"pricebnb": crypto_data[i]["price_BNB"],
}
return data

print(get_prices())编辑：

data = None
for i in crypto_data:
