这是一个 TypeError 异常,意思是函数 `Reader.read_many()` 的参数数量应该是 1 至 3 个,但是实际传入了 4 个参数。这个错误通常发生在我们使用一个函数时传入了错误的参数数量,或者传入了不符合要求的参数类型。
解决这个问题的方法是检查函数的定义和调用处的参数数量是否一致,并且确保传入的参数类型正确。你可以查看函数的文档或者代码实现来确定正确的参数数量和类型。如果你无法解决这个问题,你可以考虑向社区或者开发者寻求帮助。

TypeError: RectChart.__init__() takes from 1 to 2 positional arguments but 3 were given
This error message indicates that there is a mismatch between the number of arguments passed to the constructor of a class and the number of arguments that the constructor expects.
In this case, the class `RectChart` expects 1 or 2 positional arguments in its constructor, but 3 were given when the constructor was called. This means that there is an extra argument being passed that the class does not expect.
To fix this error, you need to check the code where the constructor is called and make sure that you are passing the correct number of arguments. Alternatively, you may need to update the constructor of the `RectChart` class to accept the additional argument.
TypeError: __init__() takes from 3 to 4 positional arguments but 5 were given
这个错误通常是因为初始化函数(__init__)的参数数量不正确导致的。
在Python中,当定义一个类时,初始化函数通常用于初始化类的属性。这个函数应该至少有一个参数,即self,它指向类的实例本身。其他参数应该用来初始化类的属性。例如:
```python
class MyClass:
def __init__(self, arg1, arg2):
self.arg1 = arg1
self.arg2 = arg2
```
当你创建一个类的实例时,你需要传递与初始化函数中定义的参数相同的数量。
例如,如果你调用以下代码:
```python
my_object = MyClass(1, 2, 3)
```
你会得到一个“TypeError: __init__() takes from 3 to 4 positional arguments but 5 were given”的错误,因为你传递了一个额外的参数(3)。
为了解决这个错误,你需要检查你的初始化函数的参数数量是否正确,并确保你在创建类的实例时传递了正确数量的参数。
