如何在Python上生成大量的随机数而不会发生冲突？

import random

def generate_random_numbers(n):
    numbers = set()
    while len(numbers) < n:
        num = random.randint(1, 1000)  # 生成1到1000之间的随机数
        if num not in numbers:
            numbers.add(num)
    return numbers

import uuid

def generate_random_numbers(n):
    numbers = set()
    while len(numbers) < n:
        num = str(uuid.uuid4())  # 生成随机的UUID
        if num not in numbers:
            numbers.add(num)
    return numbers
