url for in Flask is used for creating a URL to prevent the overhead of having to change URLs throughout an application  including in templates   Without url for  if there is a change in the root URL of your app then you have to change it in every page where the link is present   Syntax  url for  name of the function of the route   parameters  if required     It can be used as    app route   index    app route      def index        return  you are in the index page    Now if you have a link the index page you can use this    lt a href    url for  index      gt Index lt  a gt    You can do a lot o stuff with it  for example    app route   questions  lt int question id gt         int has been used as a filter that only integer will be passed in the url otherwise it will give a 404 error def find question question id         return   you asked for question 0   format question id     For the above we can use    lt a href      url for  find question   question id 1     gt Question 1 lt  a gt    Like this you can simply pass the parameters
