输出所有形如aabb的完全平方数

实现方法一

from  math import * 
for i in range(1,10):
    for j in range(1,10):
        num = 1100 * i + 11 * j
        num_sqrt = sqrt(num)
        if floor(num_sqrt) == num_sqrt:
            print(num)

实现方法二

start = 32
result = start ** 2
while result <= 10000:
    fir_2 = result // 100
    las_2 = result % 100
    #print(fir_2,las_2)
    if fir_2 % 10 == fir_2//10 and  las_2 % 10 == las_2 // 10:
        print(result)
    start += 1
    result = start ** 2
