3. Python 输出素数要输出一系列素数，你可以使用上述函数，并结合循环，来生成一系列素数。defgenerate_primes(n): primes = []for num in range(2, n+1):if is_prime(num): primes.append(num)return primes这个函数接受一个正整数 n 作为输入，然后生成从2到 n 范围内的素数，并将它们存储在一...
接下来的步骤是使用刚才的函数来找出一定范围内的所有质数。 def generate_primes(max_limit): primes = [] for num in range(2, max_limit + 1): if is_prime(num): primes.append(num) return primes 这个函数将一一检查从2到max_limit的所有数字,利用is_prime函数确定它是否为质数。如果是质数,则将其...

Python’ssympylibrary includes a function to generate prime numbers. This method is straightforward and leverages the power of existing libraries. Example: Here is a prime number program in Python. from sympy import primerange def print_primes(n): ...
