Python:ValueError:无法将字符串转换为浮点：'；44052037.79'；

您好，我收到“ValueError:无法将字符串转换为浮点：”python中的错误我知道这个错误的意思，但我无法修复它。。。我已将字符串转换为浮点，但遇到相同的错误，有人能帮我吗

#蛋糕池

蛋糕\u赌注\u url=”https://api.bscscan.com/api?module=account&action=tokenbalance&contractaddress=0x0e09fabb73bd3ade0a17ecc321fd13a19e81ce82&address=“+蛋糕池+”&标记=最新”
response=requests.get（cake\u staked\u url）
cakeurl=response.json（）
staked_cake=浮动（cakeurl['result']）/10000000000000000
桩蛋糕=浮动（桩蛋糕）固定：D

staked_cake = '{0:,.2f}'.format(float(staked_cake)) 

这就是我收到错误消息的原因：D
打印每个字符串，并检查是否可以将它们转换为float。我相信你会找到你找不到的。如果这不起作用，请告诉我
谢谢，巴德，我已经修好了。。。我在第9:D行转换字符串>浮点>字符串
