如何使用python3操作clickhouse

# pip3 install clickhouse-driver
from clickhouse_driver import Client
import random
import string
import datetime
date = datetime.datetime.today()
s_datetime = str(date.strftime("%Y-%m-%d"))

def s_gen_username():
    return random.choice('abcdefghijklmnopqrstuvwxyz')
def s_gen_pwd():
    return ''.join(random.sample('zyxwvutsrqponmlkjihgfedcba0123456789',6))
def s_gen_gender():
    i = random.randint(1,2)
    if i == 1:
        return 'man'
    else:
        return 'woman'
    
client = Client(host='127.0.0.1',port='9000',user='root' ,password='dLZWIZxt')
