Python:对象抛出参数警告

Question

我遇到了一个问题。通过下面的代码，我尝试简化大型脚本中的多个文件/json 对象。

Pointer.py

import json

class Pointers:

    def __init__(self, target_file, mode, data):
        self.target_file = target_file              # file nameand path to load/store
        self.data = data                            # data to load/store
        self.mode = mode                            # mode on the data

    # some other functions

    # Writer object for non-json files
    def sys_writer_4file(self):
        with open(self.target_file, self.mode) as write_pointer:
            handler = write_pointer.write(self.data)
        write_pointer.close()
        return handler

但是当我尝试从另一个脚本调用它时，如下所示，

Report.py

from f_pointers import Pointer

class Something:

    def someElse(self, url):
        self.url = url

    def someNonStaticFunction(self):
        path = "./filepath/filename"
        someData = data
        Pointers.sys_writer_4file(("./filepath/filename", 'wb', somedata)

我从口译员那里收到意外的参数警告，说:

This inspection reports discrepancies between declared parameters and actual arguments, as well as incorrect arguments (e.g. duplicate named arguments) and incorrect argument order. Decorators are analyzed, too.

在这一行:

Pointers.sys_writer_4file(("./filepath/filename", 'wb', somedata)

有人可以告诉我应该如何创建该对象吗？提前致谢。

您必须先启动您的类(class):

Pointers("./filepath/filename", 'wb', somedata).sys_writer_4file()
