No entendi muy bien lo de la salida, de todo modos:

Código Python:

def is_prime(n):
    return all(n % i for i in range(2, n))
 
prime_numbers = []
count = 0
current_number = 1
while count <= 1000:
    if is_prime(current_number):
        prime_numbers.append(current_number)
        count += 1
    current_number += 1
 
allowed_range = range(1, 1001)
 
index = 0
while index not in allowed_range:
    try:
        index = int(raw_input())
    except ValueError:
        continue
print prime_numbers[index]
