can only concatenate str (not “int”)to str

This error occurs when you try to concatenate a string with an integer using the "+" operator. Python doesn't allow direct concatenation of different types. To fix this, you can convert the integer to a string using the `str()` function before concatenating. Here's an example:
```python
num = 10
text = "The number is: " + str(num)
print(text)
```
Output:
```
The number is: 10
```
By converting the integer `num` to a string, we can concatenate it with the text.

这个错误提示表明你在尝试将一个整数类型的值与一个字符串类型的值进行连接(concatenation)操作。在 python 中,字符串类型和整数类型不能直接进行连接操作,需要先将整数转换为字符串类型才能进行连接。
You could try, for example converting int to str before concatenate, with str(your_int)
TypeError: can only concatenate str (not "int") to strTypeError: can only concatenate str (not "int") to str
这个错误通常发生在你试图将整数类型(int)与字符串类型(str)进行连接操作时。Python不允许直接将整数和字符串进行拼接,你需要将整数转换为字符串类型后再进行操作。例如,你可以使用内置的str()函数将整数转换为字符串。下面是一个示例:
```python
num = 10
text = "The number is: " + str(num)
print(text)
```
在上述示例中,我们使用str()函数将整数num转换为字符串类型,然后通过字符串拼接操作将其与另一个字符串进行连接。
如果你能提供更多关于你的代码的上下文或给出具体的错误提示,我可以提供更准确的帮助。
