make a web server in localhost with flask

I want to know that if I can make a web server with Flask in my pc like xampp apache (php) for after I can access this page in others places across the internet. Or even in my local network trough the wifi connection or lan ethernet. Is it possible ? I saw some ways to do this, like using "uwsgi".. something like this... but I colud never do it.

OBS: I have a complete application in Flask already complete, with databases and all things working. The only problem is that I don't know how to start the server and access by the others pc's.
