I am trying to show a validation error to the users when they try to sign up with an email or username that’s already been taken.

When submitting a form in the website, it saves the data inputted after submitting and if you reload or reopen the website, it sends a POST request and then immediately send the same data to the database.

I have a very simple webpage which is just going to read a text file listing email addresses and write them into a table. Next to each row there is a delete button to delete that specific email from the list. There is also a button to save the data in the table to a file.

I am trying to code a URL shortener website and I have ran into a problem where I am getting ‘Error’ when trying to shorten my URL. It worked and gave a test URL when there was a link in the ‘long_url’ variable on my URL Shortener.py but when I tried changing it to get the input from the HTML form, it has stopped working. Does anyone know how to correctly assign an input from an HTML form to a python variable. I will attach my files.

I recently started learning flask and i ran into an issue that happens when 1 html file has 2 forms that can be submitted. This issue does not happen when there is only one form.

Im a new coder and i dont know why even though there are no errors, nothing is appearing on my web browser! I am currently trying to create a program which can iterate through different pdf files and find keywords
