Python如果打印的结果与之前相同，则打印不更改，否则打印新结果。每10分钟再跑一次

Question

我想每10分钟运行一次这个脚本，如果今天的结果相同，我不想再次打印它们，除非它们改变。这可能吗？不，我不是程序员，这只是一种爱好

我正在使用Twilio向我发送一条适用于露营地的短信，但我不希望每10分钟收到一条相同的短信。我删除了Twilio代码，因为它有我的帐户信息。提前感谢您的帮助。下面是我的代码

from datetime import datetime
import pandas as pd
import requests
from tabulate import tabulate


result = []
for unit_id in range(5095, 5099):
    resp = requests.get(
        f"https://calirdr.usedirect.com/rdr/rdr/fd/"
        f"availability/getbyunit/{unit_id}/startdate/2020-10-30/nights/30/true?").json()
    result.extend(resp)

filter_by = ['UnitId', 'StartTime', 'IsFree', 'IsWalkin']
df = pd.DataFrame(result)
df = df.filter(items=filter_by)
df['StartTime'] = df['StartTime'].apply(lambda d: datetime.fromisoformat(d).strftime("%Y-%m-%d"))
df = df[df['IsFree']]
df = df[~df['IsWalkin']]
df['UnitId'] = df['UnitId'].replace([5095], 'Site 81')
df['UnitId'] = df['UnitId'].replace([5096], 'Site 82')
df['UnitId'] = df['UnitId'].replace([5097], 'Site 83')
df['UnitId'] = df['UnitId'].replace([5098], 'Site 84')
df['UnitId'] = df['UnitId'].replace([5099], 'Site 85')
print(tabulate(df, headers=filter_by))

下面是运行代码的结果

    UnitId    StartTime    IsFree    IsWalkin
--  --------  -----------  --------  ----------
62  Site 83   2020-11-01   True      False
80  Site 83   2020-11-19   True      False
89  Site 83   2020-11-28   True      False

这将运行程序，等待十分钟，检查上一个结果是否与当前结果相同，如果是，则退出。所以你现在要做的是弄清楚，如何在第二天之前戒掉它：）
