I have a html page with text box and submit button. When somebody enters data in text box and click submit, i have to pass that value to a python script which does some operation and print output. Can someone let me now how to achieve this. I did some research on stackoverflow/google but nothing conclusive. I have python 2.7, Windows 10 and Apache tomcat. Any help would be greatly appreciated.
Thanks,

You need to use a python web-framework of some sort. I suggest giving Django project a try. It has a great tutorial.
Short answer: You can't just run a python script in the clients browser. It doesn't work that way.
If you want to execute some python when the user does something, you will have to run a web app like the other answer suggested.

I am trying to write a program that goes to the following site and downloads the Excel file that automatically downloads when clicking the XLS button on the bottom of the page. To be honest, I am quite new to programming.
Site: https://echa.europa.eu/assessment-regulatory-needs
At first I tried using Selenium to let the program click itself through the browser and really click on the button. However, I think the website detects the usage of automated software and I cannot bypass the disclaimer that appears when opening the website.
Then I read some answers on the same topic where it is possible by using the requests module. However, I could not get it to work.
One thing I think I understood from this anwer was that you need to get the site/server where the data is requested from by inspecting the button with F12 in the browser. I tried this, and thought I had it, however I cannot get the code to function. I learnt from this answer that you need to give the referer as well, bu I think the referer from this file ist only partially written out, as it is "https://echa.europa.eu/assessment-regulatory-needs".
This answer explained the network process more in detail, howver I am not able to recreate it. Also, to be honest i do not fully understand what the API is and how to search for it.
I also found this answer, but it does not work for me either.
So I am asking for help on this, as I think that my HTML, Java, Website, Python knowledge is too tiny to see what I have to change to be able to download the excel file.
I have been working on making a python script that will run by clicking a button and then displaying the output in the Django html page. so far I have managed to make a button that will run the script but I am not able to display any results below is the code I have used, it runs the python script in shell but goes no further.
In my Views.py
def Yellow(request):
inp = request.POST.get('param')
out = run(['python', '/yellow_page_updated.py', inp], stderr=subprocess.DEVNULL)
print(out.stderr)
print("Finished!!")
return render('Yellow_Page.html', {'data1': out})
In my Urls.py
url(r'^Yellow', views.Yellow, name="Yellow")
if anybody can help or point me in the right direction i would be very grateful.
if ant other info is needed please let me know

I am looking for resources or guide so that I could build a Python code to fill my ~2k online forms automatically. Sorry I dont have any script to share as many resources in which python code is written to go to form URL and fill it. Since in my case it is a pop up form it doesnt really have a real URL.
Please be kind, I am new to Python.
Is there a way to do something to imitate clicks on browser window and fill in new values in the form ?
You can imitate clicks in the browser using selenium https://realpython.com/modern-web-automation-with-python-and-selenium/. There are plenty of tutorials how to do that.
Other tools would be:
https://www.cypress.io/
http://wwwsearch.sourceforge.net/mechanize/
If you don't want to write code - an
extension in the browser: https://www.seleniumhq.org/projects/ide/
i am writing an HTML editor and would like to make a section so that you can view how it would look in web browser directly in the program is this possible?
Thanks so much
I wouldn't do this - your renderer will quickly differ from real browsers.
