使用python编写一个模块实现加减乘除和幂运算，并包含完整的API和模块文档

以下是一个名为“basicMath”的Python模块，它实现了加减乘除和幂运算，并包含完整的API和模块文档：

# basicMath.py

"""
basicMath.py - A module for basic arithmetic operations.
"""

def add(x: float, y: float) -> float:
    """Add two numbers."""
    return x + y

def subtract(x: float, y: float) -> float:
    """Subtract two numbers."""
    return x - y

def multiply(x: float, y: float) -> float:
    """Multiply two numbers."""
    return x * y

def divide(x: float, y: float) -> float:
    """Divide two numbers."""
    if y == 0:
        raise ZeroDivisionError("division by zero")
    return x / y

def power(x: float, y: float) -> float:
    """Raise x to the power of y."""
    return x ** y

使用该模块的示例代码：

# main.py

import basicMath

print(basicMath.add(2, 3))       # Output: 5.0
print(basicMath.subtract(5, 2))  # Output: 3.0
print(basicMath.multiply(2, 4))  # Output: 8.0
print(basicMath.divide(10, 2))   # Output: 5.0
print(basicMath.power(2, 3))     # Output: 8.0

模块文档：

NAME
    basicMath.py - A module for basic arithmetic operations.

FUNCTIONS
    add(x: float, y: float) -> float
        Add two numbers.

    divide(x: float, y: float) -> float
        Divide two numbers.

    multiply(x: float, y: float) -> float
        Multiply two numbers.

    power(x: float, y: float) -> float
        Raise x to the power of y.

    subtract(x: float, y: float) -> float
        Subtract two numbers.

以上是一个简单的实现，你也可以在模块中添加更多的数学操作函数，并在文档字符串中提供更详细的说明。
