In my Command Prompt/Terminal, sometimes I see the following message:
* Running on http://127.0.0.1:5000/. So, why did you tell me to type localhost:5000/[whatever_path_name] instead in my browser?
This is because localhost is "the same" as 127.0.0.1 - essentially, it is an easier, more human-readable version of the web address
pointing to the server you are running locally.
Why do all of your template files end in .htm.j2 rather than .html?
This is purely done to make sure my template files are highlighted correctly with pretty and helpful colours in my text editor.
You may use either the htm.j2 or .html file ending. As long you are referring to the templates by the same name when using
the render_template function, everything should work as expected.
For example, if you have a template called hello.htm.j2 in the templates folder, write
render_template("hello.htm.j2")Why is it that in the hello function, it reads render_template("hello.htm.j2"), whereas in the hello_someone function,
it reads render_template("hello.htm.j2", name=name.title()) ?
The render_template function accepts an unlimited number of optional named variables after the name of the template, which when passed to the render_template function, the data/value in the named variables themselves become accessible in the template files. This
is important as it allows dynamic data to be displayed without the need to write separate HTML templates for every possible name the user may type in through the browser.
