ValueError: could not convert string to float: '15.000°'

这个错误通常是因为代码试图将一个字符串转换为浮点数,但是这个字符串包含了不能被转换的字符,例如这里的度数符号"°"。要解决这个问题,可以先将字符串中的特殊字符去掉,然后再尝试转换为浮点数。比如,如果你想将"15.000°"转换为浮点数,可以这样做:
```
string = "15.000°"
string = string.replace("°", "")
value = float(string)
```

ValueError: could not convert string to float: 'admin.'
This error is likely occurring because you are trying to convert the string 'admin.' to a float using a method such as float('admin.'). This is not possible because 'admin.' is not a valid float value.
To resolve this error, you need to ensure that you are only trying to convert valid float values to floats. Check the data you are working with to make sure that all values that you are attempting to convert to floats are actually numeric values. If there are non-numeric values mixed in with your data, you will need to clean or filter the data before attempting to convert it to floats.
ValueError: could not convert string to float: '.3f'
当使用`float()`函数将字符串转换为浮点数时,如果字符串不满足数值型的要求,就会抛出`ValueError`异常。在你提供的例子中,`ValueError`的提示是"could not convert string to float: '.3f'"。这是因为字符串".3f"不是一个有效的浮点数表示形式。
为了解决这个问题,你需要确保要转换的字符串是一个有效的数值型字符串。例如,可以使用`try...except`语句来处理可能抛出的`ValueError`异常,并提供相应的错误处理逻辑。
