def validate(n): num = str(n) length = len(num) k = 0 for i in range(length-1): for j in range(i+1, length): if num[i] == num[j]: k = 1 if k == 1: return True else: return False def isprime(x): for i in (2, int(sqrt(x))+1): if x % i == 0: return False return True if __name__ == "__main__": count = 0 n1, n2 = eval(input("input two numbers a, b(a<32767,b<32767): ")) if n1 > n2: n1, n2 = n2, n1 for i in range(n1, n2+1): if validate(i) or isprime(i): count += 1 print("{:<8}".format(i), end = "") if count % 8 != 0: print()这段代码有什么问题?

这段代码有一个问题,即在isprime函数中的for循环应该是从2到int(sqrt(x))+1,而不是从(2, int(sqrt(x))+1)。应该改为如下形式:
```
for i in range(2, int(sqrt(x))+1):
if x % i == 0:
return False
return True
```
另外,在输出格式中,应该使用format函数而不是print函数的end参数来控制输出格式。应该改为如下形式:
```
print("{:<8}".format(i), end = "")
if count % 8 == 0:
print()
```
