Flask includes the redirect function for redirecting to any url  Futhermore  you can abort a request early with an error code with abort   from flask import abort  Flask  redirect  url for  app   Flask   name      app route      def hello        return redirect url for  hello      app route   hello    def world      abort 401    By default a black and white error page is shown for each error code   The redirect method takes by default the code 302  A list for http status codes here

You have to return a redirect   import os from flask import Flask redirect  app   Flask   name      app route      def hello        return redirect  http   www example com   code 302   if   name         main           Bind to PORT if defined  otherwise default to 5000      port   int os environ get  PORT   5000       app run host  0 0 0 0   port port    See the documentation on flask docs  The default value for code is 302 so code 302 can be omitted or replaced by other redirect code  one in 301  302  303  305  and 307

From the Flask API Documentation  v  0 10       flask redirect location  code 302  Response None       Returns a response object  a WSGI application  that  if called  redirects the client to the target location  Supported codes are 301  302  303  305  and 307  300 is not supported because it   s not a real redirect and 304 because it   s the answer for a request with a request with defined If-Modified-Since headers       New in version 0 6  The location can now be a unicode string that is   encoded using the iri to uri   function       Parameters          location     the location the response should redirect to    code     the redirect status code  defaults to 302    Response  class      a Response class to use when instantiating a response  The default is werkzeug wrappers Response if unspecified

For this you can simply use the redirect function that is included in flask from flask import Flask  redirect  app   Flask   name      app route      def hello        return redirect  quot https   www exampleURL com quot   code   302   if   name       quot   main   quot       app run    Another useful tip as you re new to flask   is to add app debug   True after initializing the flask object as the debugger output helps a lot while figuring out what s wrong
