语与余

m = [0]*5
count = 0
for each in range(1,256):
    a = t = each*each
    i = 0
    while t != 0:
        m[i] = t%10
        t //= 10
        i +=1
        # print(m)
    x = 1
    f = 0
    while i > 0:
        f +=m[i-1]*x
        x *=10
        i -=1
        # print(f)
    if f == a:
        count +=1
        print(f'{count}:{each},{a}')

转换字符进行对比
for i in range(1,256):：
    m,n= '',''
    m = str(i*i)
    for j in range(len(m)):
        n +=m[len(m)-1-j]
    # print(m,n)
    if n == m:
        print(m)
