我得到了下面的文件，并希望使用参数代替。我如何在Python中传递它们？

import pandas as pd
import mysql.connector
from sqlalchemy import create_engine
from urllib.parse import quote
from io import StringIO
import smtplib, ssl
import mimetypes
from email.mime.text import MIMEText
from email.mime.multipart import MIMEMultipart
from email.mime.base import MIMEBase
from email.mime.application import MIMEApplication
from email import encoders
import logging

username = "xxxxx"
password = "yyyyyy"
port = 3306
database = "esxinfo"

engine = create_engine('mysql+mysqlconnector://test:%s@jenkins:3306/esxinfo' % quote('xxxxxx'))
sql = pd.read_sql('SELECT * FROM esx_info', engine)

df = pd.DataFrame(sql)
textStream = StringIO()
df.to_csv(textStream,index=False)

def sendmail():
    msg = MIMEMultipart()
    my_address ="mygmail@gmail.com"
    app_generated_password = "xxxxxxxxxxxx" 
    msg['Subject'] = "The Email Subject"
    msg["From"]= my_address
    msg['To'] = "yyyyyyyyyyy
    msg.add_header('Content-Type','text/html')
    #msg.set_content("This is the body of the email") 
    #msg.attach(MIMEText(message, 'html'))
    textStream = StringIO()
    df.to_csv(textStream,index=False)
    msg.attach(MIMEApplication(textStream.getvalue(), Name="test.csv"))
    with smtplib.SMTP_SSL("smtp.gmail.com", 465) as smtp:
            smtp.login(my_address,app_generated_password)    #login gmail account
            print("sending mail")
            smtp.send_message(msg)   #send message 
            print("mail has sent")

sendmail()

说我想通过

my_address ="mygmail@gmail.com"

我该怎么做而不需要输入代码呢？我想用Jenkins的参数运行这个程序。
