如何使用 windows 任务调度程序调度 python 脚本以发送 email

Question

I have a python script that scrapes a website and I want to send the data by email every day at 7:00 AM when i run the script the email is send and the function work perfect, but when I tried to use windows Task Scheduler in为了自动化它不运行的脚本。

代码：

import time
import pandas as pd
from datetime import date

import requests
from bs4 import BeautifulSoup

import smtplib
from email.mime.multipart import MIMEMultipart
from email.mime.text import MIMEText
from email.mime.base import MIMEBase
from email import encoders
from email.utils import formatdate



def scrap_website():
    soup = BeautifulSoup(
        requests.get("https://www.bayt.com/en/international/jobs/executive-chef-jobs/").content,
        "lxml"
    )

    links = []
    for a in soup.select("h2.m0.t-regular a"):
        if a['href'] not in links:
            links.append("https://www.bayt.com"+ a['href'])
    joineddd = []

    for link in links:
        s = BeautifulSoup(requests.get(link).content, "lxml")
        jobdesc=s.select_one("div[class='card-content is-spaced'] p")

        alldt = [dt.text for dt in s.select("div[class='card-content is-spaced'] dt")]
        dt_Job_location =              alldt[0]
        dt_Job_Company_Industry =      alldt[1]
        dt_Job_Company_Type =          alldt[2]
        if len(alldt[3])>0:
            dt_Job_Job_Role =              alldt[3]
        elif len(dt_Job_Employment_Type)>0:
            dt_Job_Employment_Type =       alldt[4]
                
        alldt.append("link")
        alldt.append("description")
        
        
        alldd = [dd.text for dd in s.select("div[class='card-content is-spaced'] dd")]
        dd_job_location =             alldd[0]
        dd_job_Company_Industry =     alldd[1]
        dd_job_Company_Type =         alldd[2]
        if len(alldd[3])>0:
            dd_job_Job_Role =             alldd[3]
        elif len(dd_job_Employment_Type)>0:
            dd_job_Employment_Type =      alldd[4]
        
        alldd.insert(0,link)
        alldd.insert(1,jobdesc)
        joineddd.append(alldd)    
        print("-" * 80) 
    
    convert_to_dataFrame(joineddd)
    send_email()


def convert_to_dataFrame(joineddd):
    df = pd.DataFrame(joineddd,columns=["link","description","location","Company_Industry","Company_Type","Job_Role","Employment_Type"])
    df_to_excel = df.to_excel(r"F:\\AIenv\web_scrapping\\jobDesc.xlsx", index = False, header=True)


'''send email '''
def send_email():
    today = date.today()
    file = 'F:\\AIenv\web_scrapping\\jobDesc.xlsx'
    username='xxxxxxx'
    password='xxxxxxx'
    send_from = 'xxxxxxxxxxx'
    send_to = 'xxxxxxxxxxxxxx'
    Cc = 'recipient'
    msg = MIMEMultipart()
    msg['From'] = send_from
    msg['To'] = send_to
    msg['Cc'] = Cc
    msg['Date'] = formatdate(localtime = True)
    msg['Subject'] = 'Hello, This is a test mail {}'.format(today)
    server = smtplib.SMTP('smtp.gmail.com')
    port = '587'
    fp = open(file, 'rb')
    part = MIMEBase('application','vnd.ms-excel')
    part.set_payload(fp.read())
    fp.close()
    encoders.encode_base64(part)
    part.add_header('Content-Disposition', 'attachment', filename='jobs Description--{}'.format(today))
    msg.attach(part)
    smtp = smtplib.SMTP('smtp.gmail.com')
    smtp.ehlo()
    smtp.starttls()
    smtp.login(username,password)
    smtp.sendmail(send_from, send_to.split(',') + msg['Cc'].split(','), msg.as_string())
    smtp.quit()
    print('Mail Sent')

在 windows 任务调度器中：

我按照这些步骤创建触发器以运行脚本。

我遇到了问题，在 Exec 标记中，您必须将完整的 python 路径添加到命令

当前代码：

 <Exec>
  <Command>F:\AIenv\web_scrapping\job_desc_email.py</Command>
</Exec>

推荐代码：

假设 C:\python39\python.exe 是您的 python 的路径

<Exec> <Command>C:\\python39\\python.exe F:\\AIenv\\web_scrapping\\job_desc_email.py</Command> </Exec>

因为在 Windows 操作系统中，.py 文件不与 python.exe 相关联，例如 Linux 和 Macs 操作系统。 因此，要运行 python 脚本，您应该使用以下格式命令：

{path-to-your-python.exe} {path-to-your-python-script}
