Open http://localhost:5000/ in your webbrowser, and “Hello World!” should appear.
Creating URL routes
URL Routing makes URLs in your Web app easy to remember. We will now create some URL routes:
Copy the code below and save it as app.py
Restart the application using:
Try the URLs in your browser:

Passing Variables
Lets display random quotes instead of always the same quote. We will need to pass both the name variable and the quote variable. To pass multiple variables to the function, we simply do this:
Our new test.html template will look like this:
We will need to pick a random quote. Mac osx el capitan offline download. To do so, we use this code:
The first thing you see is we have defined an array of multiples quotes. These can be accessed as quote[0], quote[1], quote[2] and so on. The function randint() returns a random number between 0 and the total number of quotes, one is subtracted because we start counting from zero. Finally we set the quote variable to the quote the computer has chosen. Copy the code below to app.py:
When you restart the application it will return one of these quotes at random.
