Best way is to Use a Python Web Frame Work you can choose Django/Flask. I will suggest you to Use Django because it's more powerful. Here is Step by guide to get complete your task :

pip install django
django-admin createproject buttonpython

then you have to create a file name views.py in buttonpython directory.

write below code in views.py:

from django.http import HttpResponse

def sample(request):
    #your python script code
    output=code output
    return HttpResponse(output)

Once done navigate to urls.py and add this stanza

from . import views

path('', include('blog.urls')),

Now go to parent directory and execute manage.py

python manage.py runserver 127.0.0.1:8001

Since you asked for a way to complete this within an HTML page I am answering this   I feel there is no need to mention the severe warnings and implications that would go along with this    I trust you know the security of your  py script better than I do  -    I would use the  ajax   function in the jQuery library   This will allow you to call your Python script as long as the script is in the publicly accessible html directory       That said this is the part where I tell you to heed security precautions        lt  DOCTYPE html gt   lt html gt     lt head gt         lt  head gt     lt body gt       lt input type  button  id  script  name  scriptbutton  value   Run Script   onclick  goPython    gt        lt script src  http   code jquery com jquery-3 3 1 min js  integrity  sha256-FgpCb KJQlLNfOu91ta32o NMZxltwRo8QtmkMRdAu8   crossorigin  anonymous  gt  lt  script gt        lt script gt          function goPython                  ajax                 url   MYSCRIPT py                context  document body                done function                  alert  finished python script                                    lt  script gt     lt  body gt   lt  html gt    In addition    It s worth noting that your script is going to have to have proper permissions for  say  the www-data user to be able to run it     A chmod  and or a chown may be necessary

It is discouraged and problematic yet doable  What you need is a custom URI scheme ie  You need to register and configure it on your machine and then hook an url with that scheme to the button    URI scheme is the part before     in an URI  Standard URI schemes are for example https or ftp or file  But there are custom like fx  mongodb  What you need is your own e g  mypythonscript  It can be configured to exec the script or even just python with the script name in the params etc  It is of course a tradeoff between flexibility and security   You can find more details in the links   https   support shotgunsoftware com hc en-us articles 219031308-Launching-applications-using-custom-browser-protocols   https   msdn microsoft com en-us library aa767914 v vs 85  aspx  EDIT  Added more details about what an custom scheme is

I ve done exactly this on Windows   I have a local  html page that I use as a  dashboard  for all my current work   In addition to the usual links  I ve been able to add clickable links that open MS-Word documents  Excel spreadsheets  open my IDE  ssh to servers  etc   It is a little involved but here s how I did it      First  update the Windows registry   Your browser handles usual protocols like http  https  ftp   You can define your own protocol and a handler to be invoked when a link of that protocol-type is clicked   Here s the config  run with regedit    HKEY CLASSES ROOT mydb     URL MyDB Document   URL Protocol       HKEY CLASSES ROOT mydb shell     open    HKEY CLASSES ROOT mydb shell open    HKEY CLASSES ROOT mydb shell open command     wscript C   opt Dashboard Dashboard vbs    1      With this  when I have a link like  lt a href  mydb open ProjectX docx  gt ProjectX lt  a gt   clicking it will invoke C   opt Dashboard Dashboard vbs passing it the command line parameter open ProjectX docx   My VBS code looks at this parameter and does the necessary thing  in this case  because it ends in  docx  it invokes MS-Word with ProjectX docx as the parameter to it   Now  I ve written my handler in VBS only because it is very old code  like 15  years    I haven t tried it  but you might be able to write a Python handler  Dashboard py  instead   I ll leave it up to you to write your own handler   For your scripts  your link could be href  mydb runpy whatever py   the runpy  prefix tells your handle to run with Python

Using a UI Framework would be a lot cleaner  and involve fewer components    Here is an example using wxPython   import wx import os class MyForm wx Frame       def   init   self           wx Frame   init   self  None  wx ID ANY   Launch Scripts           panel   wx Panel self  wx ID ANY          sizer   wx BoxSizer wx VERTICAL          buttonA   wx Button panel  id wx ID ANY  label  App A   name  MYSCRIPT           buttonB   wx Button panel  id wx ID ANY  label  App B   name  MYOtherSCRIPT           buttonC   wx Button panel  id wx ID ANY  label  App C   name  SomeDifferentScript           buttons    buttonA  buttonB  buttonC           for button in buttons              self buildButtons button  sizer           panel SetSizer sizer       def buildButtons self  btn  sizer           btn Bind wx EVT BUTTON  self onButton          sizer Add btn  0  wx ALL  5       def onButton self  event                       This method is fired when its corresponding button is pressed  taking the script from it s name                     button   event GetEventObject            os system  python    py  format button GetName              button id   event GetId           button by id   self FindWindowById button id          print  The button you pressed was labeled      button by id GetLabel           print  The button s name is     button by id GetName      Run the program if   name         main         app   wx App False      frame   MyForm       frame Show       app MainLoop     I haven t tested this yet  and I m sure there are cleaner ways of launching a python script form a python script  but the idea I think will still hold  Good luck
