连接字符串然后打印

Question

print ("Tag Value " + i.tags.get('Name'))

给我:

  File "./boto_test.py", line 19, in main
    print ("Tag Value" + i.tags.get('Name'))
TypeError: cannot concatenate 'str' and 'NoneType' objects

这样做的正确方法是什么？

Answer 1

或者只是转换无论你get从i.tags字符串:

print ("Tag Value " + str(i.tags.get('Name')))
