Python generates time and randomly generates strings according to the time range

import datetime
import random
import time

MINTIME = datetime.datetime(2022, 2, 11, 0, 0, 0) # Set the start time of the time range
MAXTIME = datetime.datetime(2022, 2, 12, 0, 0, 0) # Set the end time of the time range
mintime_ts = int(time.mktime(MINTIME.timetuple()))
maxtime_ts = int(time.mktime(MAXTIME.timetuple()))

for RECORD in range(10): # This part can also be divided into def and for, such as ggenerate_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' # Can generate strings and add features as needed
    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): # loop to generate multiple random strings
    data = generate_random_str(4)   
    print(data)
