can only concatenate str (not "float") to str

This error message occurs when you try to concatenate a string and a float value using the "+" operator in Python. In Python, you can only concatenate two strings using the "+" operator. You can convert the float value to a string using the str() function before concatenating it with another string. Here's an example:
```
x = 3.14
message = "The value of x is " + str(x)
print(message)
```
Output:
```
The value of x is 3.14
```
In this example, the float value of x is first converted to a string using the str() function, and then concatenated with the string "The value of x is " using the "+" operator.

can only concatenate str (not float
)。
这个错误提示意味着你正在尝试将一个字符串和一个浮点数连接起来,但是这是不允许的。可能是因为你在代码中使用了加号(+)来连接两个变量,但是其中一个变量的类型是字符串,另一个变量的类型是浮点数。要解决这个问题,你可以将浮点数转换为字符串,然后再进行连接操作。例如,可以使用 str() 函数将浮点数转换为字符串,然后再进行连接操作。
can only concatenate str (not "float")
This error occurs when you try to concatenate a string with a float value. In Python, you can only concatenate strings with strings. To resolve this error, you need to convert the float value to a string before concatenating it. Here's an example:
```
float_value = 3.14
string_value = "The value is: " + str(float_value)
print(string_value)
```
In this example, the `str()` function is used to convert the float value to a string before concatenating it with the rest of the string.
