自定义写sort排序函数，实现排序

[python]代码库

lst = [1,3,2,5,6,4]

def sort(iterable,key=lambda a,b:a<b,reverse=False):
    ret = []
    for x in iterable:
        for i, y in enumerate(ret):
            flag = key(x,y) if reverse else key(y,x)
            if flag:
                ret.insert(i,x)
                break
        else:
            ret.append(x)
    return ret

print(sort(lst))
