关于#python#的问题，如何解决？

Question

数据可以接收到，但是显示不能由字典转化为字符串（希望得到代码）

Traceback (most recent call last):
  File "C:\lin\python\lib\threading.py", line 932, in _bootstrap_inner
    self.run()
  File "D:\新建文件夹\zhsy_test1\app\widgets\mythread2.py", line 50, in run
    str(self.data_decoding(self.data[i]))
  File "D:\新建文件夹\zhsy_test1\app\widgets\mythread2.py", line 24, in data_decoding
    print("接收到数据："+data1)
TypeError: can only concatenate str (not "dict") to str

Answer 1

data1是字典类型，不能直接和字符串拼接。
