urlshort | Ex 2 - Create an http.Handler that forwards paths | Runtime Evironment library

I can't see your data set, but I think pandas to_dict('records') is returning you a list of dict (which you are storing as dict_copy). Then when you iterate through that with for r in dict_copy: r isn't a URL, but a dict that contains the URL in some way. So str(r) converts that dict {} to '{}', and you are then sending that off as your URL.

I think that's why you are seeing the error URLError:

Adding a print statement after the df dump (print(dict_copy) right after dict_copy = df.to_dict('records')), and at the beginning of your iteration (print(r) right after for r in dict_copy:) would help you see what's going on and test/confirm my hypothesis.

Thanks for adding sample data! So dict_copy is something like [{'urlReady': 'mobile.****.***.**/****/43153.jpg'}, {'urlReady': 'mobile.****.***.**/****/46137.jpg'}]

So yes, dict_copy is a list of dict, looking like 'urlReady' as the key and a URL string as a value. So you want to retrieve the url from each dict using that key. The best approach may depend on things like whether you have stuff in the data without valid URLs, etc. But this can get you started and provide a little view of the data to see if anything is weird:

There is special class for "found" redirect you can use - HttpResponseRedirect redirect instead:

You can't use configure method with Entry widget. You should instead clear the Entry, and then insert your string like this :

It's due to 301 redirects. header('HTTP/1.1 301 Moved Permanently'); So once browser gets a 301 status code for any URL say A->B it will internally "remember" the translation and therefore use that in subsequent hits So never hits A actually when user types in A in the address bar or clicks links for A

What you rather need is 302 header('HTTP/1.1 302 Found'); because browser won't cache it and your route would get hit everytime

I managed to fix the problem, the solution was to pass app to test_invalid_link:
