Is it possible to send an email from a github page with python? [duplicate]

I want to run a python file in the web I have in a GitHub repository. Is it possible to do this?

And by running in the web, I mean putting #!/usr/bin/python and print 'Content-type:text/html\n in the first two lines.

In general this is not possible, Github (pages) serves only static content (ex: HTML, CSS, JS). If you want python to run (ex generate dynamic content) you need a web server capable of running python (your browser were the contents of GitHub Pages get downloaded and run can't do it).

That said there are experimental ways of running subsets of python in the browser. Take a look for a example at this question.
