输入格式是 W1=input() W2=input() 将两个数列的数据的差 然后按升序排列 结果用"[""]"括起来 每个数据之间加","

def minus(a,b):
    c = [i for i in a if i not in b]
    c.extend(i for i in b if i not in a)
    c.sort()
    return c
a=input()
W1=a.split(" ")
b=input()
W2=b.split(" ")
print("[",end="")
for i in range(len(minus(W1,W2))):
    if i == len(minus(W1,W2))-1:
        print(minus(W1,W2)[i],end="")
    else:
        print(minus(W1,W2)[i],",",end="")
print("]")
