拼成一行代码~

print("号码：",[r*r for r in range(1,100) if ((r*r>999) and (r*r<10000) and (int(r*r/1000)==int(r*r/100%10) and int(r*r/1000)!=int(r*r/10%10) and int(r*r/10%10)==r*r%10))])

[print("号码:",r*r) for r in range(1,100) if ((r*r>999) and (r*r<10000) and (int(r*r/1000)==int(r*r/100%10)!=int(r*r/10%10) and int(r*r/10%10)==r*r%10))]
复制代码

再改成这样。

改进，排除a=b，不再使用类型转换
aabb=[r*1000+r*100+s*10+s for r in range(1,10) for s in range(1,10) if (r!=s)]
[print("号码:",r*r) for r in range(1,100) for ab in aabb if r*r==ab]
