A prime number is a natural number greater than 1 that cannot be formed by multiplying two smaller natural numbers. For example, the numbers 2, 3, 5, 7, 11, and 13 are prime numbers because they have no divisors other than 1 and themselves. Print Prime Numbers from 1 to N in Python...
print("%d is a prime number!" % n) 1. 那么此时,所有代码就写好了,不过为了看起来简单,没有罩一层是否大于1的判断,用户输入的数字默认需要大于1:n = int(input("please enter the number:")) for i in range(2, n): if n % i == 0: print(" %d is not a prime number!" % n) break...
Otherwise, the number is prime. You can change the value of variable num in the above source code to check whether a number is prime or not for other integers. In Python, we can also use the for...else statement to do this task without using an additional flag variable. Example 2: ...
【Python】is_prime number 对于一个素数的判定,一般来说是除了一和自身以外不可以被其他数整除。但是换一种方式想,这是两种情况,如果这个数本身就是1,那么不是素数,如果能被2或者以上的数字整除,意味着判断范围可以从2-自身减少到2-自身/2 如下: def is_prime(x):...
