python按照时间范围生成时间及随机生成字符串

import datetime
import random
import time

MINTIME = datetime.datetime(2022, 2, 11, 0, 0, 0)    # 设置时间范围的开始时间
MAXTIME = datetime.datetime(2022, 2, 12, 0, 0, 0)    # 设置时间范围的结束时间
mintime_ts = int(time.mktime(MINTIME.timetuple()))
maxtime_ts = int(time.mktime(MAXTIME.timetuple()))

for RECORD in range(10):              # 这部分也可以才分为def和for，如gnerate_random_str
    random_ts = random.randint(mintime_ts, maxtime_ts)
    RANDOMTIME = datetime.datetime.fromtimestamp(random_ts)
    print(RANDOMTIME)

def generate_random_str(datalength):
    random_str = ''
    base_str = 'abcdefghijklmnopqrstuvwxyz0123456789'  # 可以根据需要生成字符串特点添加
    length = len(base_str) - 1
    for i in range(datalength):
        random_str += base_str[random.randint(0, length)]
    return random_str

for i in range(500):        # 循环实现生成多个随机字符串
    data = generate_random_str(4)   
    print(data)
