使用 os.environ 访问环境变量？

Question

I'm trying to access the email address and email password of the current user environment but when I try to print the herein variables 'EMAIL_ADDRESS' and 'EMAIL_PASSWORD', I get None values.

I'm using an Android phone to code this simple project. Here is it:

import os
import smtplib

EMAIL_ADDRESS = 
os.environ.get('EMAIL_USER')
EMAIL_PASSWORD = os.environ.get('EMAIL_PASS')


subject = 'Practice email code'
body = 'This is my 1st output'
msg = f'Subject:{subject}\n{body}'



server = 
smtplib.SMTP('smtp.gmail.com', 587)
server.ehlo()
server.starttls()
server.login(EMAIL_ADDRESS, EMAIL_PASSWORD)




server.sendmail(EMAIL_ADDRESS, EMAIL_PASSWORD, msg)
server.close()

Almost similar questions I've found here in StackOverflow have received a suggestion to make a new file containing the email ad and password. But is there a way to not cross with this solution? If none, what's the best you could recommend for a beginner to approach this problem? I don't have any much goal as I am yet to have a solid introductory skill. So as long as I could send the email through using the object 'os.environ' to access my email ad and password, I'm good to go.

Any suggestion will be appreciated!

That is not Python's problem. Try writing bash script to see if the two variables are really defined.
