编程输入一位三位数，输出小于它的所有素数组成的列表。

Question

要求：使用enumerate() 和filter()

Answer 1

from math import sqrt

def isPrime(m):
    for i in range(2, int(sqrt(m) + 1)):
        if m % i == 0:
            return False
    return True

n=int(input("Please enter a 3-digit number: "))

for index, item in enumerate(filter(isPrime, list(range(2, n)))):
    print(f"The {index}th prime number less than {n}: {item}")
