在上面的代码中,我们使用np.floor函数将索引数组idx向下取整,并使用astype(int)将其转换为整数类型数组。这样就可以避免出现“TypeError: only integer scalar arrays can be converted to a scalar ind”错误。 2. 检查索引数组的类型 另一种解决方法是检查索引数组的类型,并确保它是整数类型的。可以使用dtype属性...
We thus want one of n-1 and n+1 to be a prime and the other to be a product of two primes. All of these primes have to be odd since n-1 and n+1 have the same parity and there exists only one even prime.Call a positive integer a ‘semiprime’ if it is the product of ...
