自定义列表使支持四则运算py

可以使用Python中的类来自定义一个支持四则运算的列表。具体实现方法如下：

class ArithmeticList(list):
    def __init__(self, *args):
        super().__init__(*args)

    def __add__(self, other):
        if isinstance(other, ArithmeticList):
            return ArithmeticList([x + y for x, y in zip(self, other)])
        else:
            return NotImplemented

    def __sub__(self, other):
        if isinstance(other, ArithmeticList):
            return ArithmeticList([x - y for x, y in zip(self, other)])
        else:
            return NotImplemented

    def __mul__(self, other):
        if isinstance(other, ArithmeticList):
            return ArithmeticList([x * y for x, y in zip(self, other)])
        else:
            return ArithmeticList([x * other for x in self])

    def __truediv__(self, other):
        if isinstance(other, ArithmeticList):
            return ArithmeticList([x / y for x, y in zip(self, other)])
        else:
            return ArithmeticList([x / other for x in self])

    def __floordiv__(self, other):
        if isinstance(other, ArithmeticList):
            return ArithmeticList([x // y for x, y in zip(self, other)])
        else:
            return ArithmeticList([x // other for x in self])

    def __mod__(self, other):
        if isinstance(other, ArithmeticList):
            return ArithmeticList([x % y for x, y in zip(self, other)])
        else:
            return ArithmeticList([x % other for x in self])

    def __pow__(self, other):
        if isinstance(other, ArithmeticList):
            return ArithmeticList([x ** y for x, y in zip(self, other)])
        else:
            return ArithmeticList([x ** other for x in self])

这个类继承了Python内置的list类，并通过重载运算符（例如`__add__`、`__sub__`等）来实现四则运算。例如：

a = ArithmeticList([1, 2, 3])
b = ArithmeticList([4, 5, 6])
c = a + b
print(c) # [5, 7, 9]
d = a * 2
print(d) # [2, 4, 6]

这个类还支持和普通的数值类型进行运算。例如：

a = ArithmeticList([1, 2, 3])
b = a + 2
print(b) # [3, 4, 5]

注意，这个类只实现了简单的四则运算，没有实现复杂的运算（例如求导、积分等）。如果需要实现更加复杂的运算，可以考虑使用Python中的符号计算库（例如SymPy）。
