sending email using python after checking some condition

I am trying to build a prototype in python. The used case is fairly simple. Upon running the program will accept an input x and will execute something like

if(x<=3){
  send email to xxx@gmail.com
  some html copy
} 

This is the start...Now I think I would need a web server to send an email. And that's where I getting lost. Can I avoid installing a server stack for this task? I am pretty new to python.
