Python利用柯里化实现提高代码质量

def add(x, y):
    return x + y
 
result = add(3, 5)  # 结果为 8

def add(x):
    def add_x(y):
        return x + y
    return add_x
 
add_3 = add(3)
result = add_3(5)  # 结果为 8

def curry(func):
    def curried(*args, **kwargs):
        if len(args) + len(kwargs) >= func.__code__.co_argcount:
            return func(*args, **kwargs)
        return lambda *more_args, **more_kwargs: curried(*(args + more_args), **{**kwargs, **more_kwargs})
    return curried
 
# 定义一个多参数函数
def add(x, y, z):
    return x + y + z
 
# 使用柯里化将其转化为单参数函数的组合
curried_add = curry(add)
 
add_1 = curried_add(1)
add_2 = add_1(2)
result = add_2(3)  # 结果为 6

def multiply(x, y):
    return x * y
 
double = curry(multiply)(2)  # 部分应用参数，创建一个乘以2的函数
 
result = double(5)  # 结果为 10

def apply_operation(operation):
    def apply(data):
        return [operation(x) for x in data]
    return apply
 
# 创建一个平方函数
square = curry(apply_operation)(lambda x: x ** 2)
 
data = [1, 2, 3, 4, 5]
result = square(data)  # 结果为 [1, 4, 9, 16, 25]

# 创建一个处理点击事件的回调函数
on_click = curry(on_event)('click')
