我想用字符串方式為什么這樣不可以
L['1','2','3','4','5','6','7','8','9']
A['0','1','2','3','4','5','6','7','8','9']
print [a + b + c for a in A for b in L for c in L if a == c]

字符串組合成的就不是 數字 了，而是字符串，
你用L=[1,2,3,4,5,6,7,8,9],A=[0,1,2,3,4,5,6,7,8,9]
而且應該是for a in L for b in A for c in A，頭一個數字不能為0，其他兩個數字可以為0

要的是對稱數，你得出的是字符串
