我需要在Python中生成1000个唯一的名字

import uuid

names = []
for _ in range(1000):
    name = uuid.uuid4().hex[:8]
    names.append(name)

import random
import string

names = []
for _ in range(1000):
    name = ''.join(random.choices(string.ascii_letters + string.digits, k=8))
    names.append(name)

import time
import random
import string

names = []
timestamp = str(int(time.time()))
for _ in range(1000):
    random_string = ''.join(random.choices(string.ascii_letters + string.digits, k=4))
    name = timestamp + random_string
    names.append(name)
