checkArm函数：求是否是水仙数

def checkArm(m):
    m = str(m)
    tN = list(m)
    sum = 0
    for i in range(0,len(tN)):
        sum = sum + int(tN[i])**len(tN) #这边用map也行
    if sum == int(m):
        return True
    else:
        return False

输入Max求100到Max中的水仙数

alist = []
max = int(input('input max > 1000 :'))
def findArm(max):

    for i in range(100,int(max)):
        if checkArm(i) == True:
            alist.append(i)
findArm(max)
print(alist)

求并集

aset = set(input('input string A:'))
bset = set(input('input string b:'))
print(aset | bset)
