If you look closely, the argument we’re passing is an array. You can pass one or more methods allowing one route to handle one or several methods differently. Here, we’re locking the root route function to the HTTP GET method, which is what your browser issues when you visit a site.

Next, we’ve added Flask’s render_template method to our import. I changed the name of the function from hello_world to root, then I changed the return from the 'Hello World' string to the result of the render_template function that takes the filename of a template. Flask knows to find index.html in the Templates folder.

Now we’re ready to try it out. Make sure your Flask app is selected in the run configuration dropdown and click the green Run button. The Run tab will appear at the bottom of the PyCharm screen. Mine appears as shown in Figure 8.11.
