Python 3 : What am I doing wrong here?

Question

这个问题已经有答案了:

TypeError: worker() takes 0 positional arguments but 1 was given [duplicate] (11 个回答)

这是我的代码的精简版本。当我尝试执行它时，我得到:

Traceback (most recent call last): File "test.py", line 16, in value = oss.get() TypeError: get() takes 0 positional arguments but 1 was given

import os

class OsyncStateSerial():
        """Reads and writes current state serial for local replica"""

        def __init__(self, oss_file):
                if os.path.exists(oss_file):
                        pass
        def ranget():
                return 1

        def ranset():
                return 0

oss = OsyncStateSerial("somefile")
value = oss.ranget()
print(value)

我做错了什么？

您需要在类方法中包含参数 self:

import os

class OsyncStateSerial():
        """Reads and writes current state serial for local replica"""

        def __init__(self, oss_file):
                if os.path.exists(oss_file):
                        pass
        def ranget(self):
                return 1

        def ranset(self):
                return 0

oss = OsyncStateSerial("somefile")
value = oss.ranget()
print(value)

输出
