Python進階1---高階函數、柯里化

高階函數

不相等

 自定義sort函數

內建函數--高階函數

 

 

#sort函數
def sort2(lst,key = None,reverse = False):
    res = []
    if key is None:
        key =lambda x,y:x<y
    if reverse:
        key = lambda x,y:x>y
    for x in lst:
        for j,y in enumerate(res):
            if key(x,y):
                res.insert(j,x)
                break
        else:
            res.append(x)
    return res

def filter1(predict,lst):#filter1至關於(item for item in iterable if function(item))
    if predict is None:
        predict = bool

    for i in lst:
        if predict(i):
            yield i

#簡單實現map函數
def map1(predict,lst):
    for args in lst:
        yield predict(*args)
