TypeError: write_files_to() got multiple values for argument 'data'

TypeError: write_files_to() got multiple values for argument ‘data’

执行python的时候遇到这个错误：

原代码：

def write_files_to(self,files=None,data=None,run_as_root=False,timeout=120, create=True,*files,**data)

调用的时候：

r = client.call({}, "write_files_to", files=["/tmp/test","/tmp/test1"],
                data=base64.b64encode(b'1234'))

这个时候就报出上述错误：
Traceback (most recent call last):

File “/root/codes/sahara-agent/.tox/venv/lib/python3.6/site-packages/oslo_messaging/rpc/server.py”, line 165, in _process_incoming

TypeError: write_files_to() got multiple values for argument ‘files’

原因：

函数传入的参数是一个list，默认成了传入的是两个参数值，导致在调用时以为传入两个参数，从而报错

解决：

确实要传多个参数：可以利用python传参的性质（*files,**data），这样写就可以通过：
def write_files_to(self,run_as_root=False,timeout=120, create=True,*files,**data):
