Learning Flask Installing and Using Routes Templates Errors

Flask is a microframework for server-side web development in python.

Errors

In Flask, routes normally work with render_template() to react according to HTTP status codes . That is, a normal response is 200 and errors happen in 4XX and 5XX range.

Because 200 is the default, it is not needed for a normal response. However, the most correct response would be to return the code “200” along with any textual data.

Handling Errors

Along with route() , there is also the errorhandler() function. This takes as a parameter the status code or the name of a known exception.

In order to pass back the error, the code should also be returned. This allows the server to correctly register the error to the user.

However, the render_template() can also be used to deliver specific error files or templates along with any other reactions.
