#whatever you name it
#but when importing the file the name will be the name you named it

#which is equal to __main__
#so we have to make sure it runs only from this file

#127.0.0.1:5000
#to open your website
#you can change the host by passing in the host as an str
#in the app.run()
#e.g app.run("host")
#and you can also change the port
#e.g app.run("host",8464)
#this will open on host:8464
