由于代码中的这一部分,我无法编译:
if command == 'HOWMANY':
opcodegroupr = "A0"
opcoder = "85"
elif command == 'IDENTIFY':
opcodegroupr = "A0"
opcoder = "81"
我有这个错误:
抱歉:IndentationError: ('unndent does not match any external indentation level', ('wsn.py', 1016, 30, "\t\telif command == 'IDENTIFY':\n"))
但我没有看到任何缩进错误。可能是什么问题?
