I am coming from a php background using standard cpanel webhosts to produce a simple website in html. The background work is in php, for example, I write some simple php code in a text editor, save it with .php extension, upload it to the file directory - for example hello.php --> and when I visit my website mysite-dot-com/hello.php in browser I can see simply HELLO WORLD in the web browser. Its not clear to me how do I do this simple thing here in python. For example, do I write a file and save it with .py extension ... Next where do I upload it or save it? And now do I visit mysite-dot-com/hello.py and see HELLO WORLD in the web browser.? Thanks
