解决Python 异常TypeError: cannot concatenate str and int objects

TypeError: cannot concatenate ‘str’ and ‘int’ objects print str + int 的时候就会这样了 python + 作为连接符的时候，不会自动给你把int转换成str 补充知识：TypeError: cannot concatenate ‘str’ and ‘list’ objects和Python读取和保存图片运行程序时报错，然后我将list转化为str就好了。利用”.join(list) 如果需要用逗号隔开，如1,2,3,4则使用’,’.join(list) Python中plt可以显示和保存图片，不能使用mping

This error occurs when you try to concatenate a string and a float using the + operator. Python does not allow this operation as it requires both operands to be of the same data type. To fix this error, you need to convert the float to a string before concatenating it with the other string. You can do this using the str() function. Here's an example: ``` x = 3.14 s = "The value of pi is " + str(x) print(s) ``` Output: ``` The value of pi is 3.14 ``` In this example, the float value of pi is converted to a string using the str() function before it is concatenated with the other string.
