Where?
#1
Hello everyone
I would really like to start learning Python3 but to be honest i am a little confused and hope that someone will have the time and patience to explain a question i have:

When using for example JavaScript or PHP you can embed the scripts within the HTML. Where would you place a python script prior to execution?

Hope you don't mind me asking this silly question.

If your using wsgi or similar you can put the script anywhere. You would just tell Apache where the scripts are located.

You can also use a web framework like Django, Bottle, Flask.

The closet way to the workflow in PHP(with HTML/CSS/JavaScript) is to use eg Flask.
To give a demo that i have posted before,install is pip install Flask .
This is all you need for local development(Flask has build in web server),forget about WAMP,LAMP or XAMPP as you may have used in PHP.

Setup folder/files:
my_app
  |-- app.py
  templates\
    |-- index.html
    |-- about.html
  static\
    css\
      |-- style.css
    js\
    img\ 
app.py:
from flask import Flask, render_template, jsonify, request
 
app = Flask(__name__)
@app.route('/')
def index():
   return render_template("index.html")
 
@app.route('/about',  methods=['GET'])
def about():
   return render_template("about.html") 

if __name__ == '__main__':
   app.run(debug=True)
index.html:
<!doctype html>
<html>
  <head>
     <meta charset="UTF-8">
    <title>Some title</title>
    <link rel=stylesheet type=text/css href="{{ url_for('static', filename='css/style.css') }}" />
  </head>
  <body>
    <div id="start">
      <h1>Start page</h1>
      <ul>
        <li class="page_1"><a href="/about">About</a></li>
      </ul>
    </div>
  </body>
</html>
about.html:
<div class="foo">
  <h1>The About Page</h1>
  <a href="https://python-forum.io/">Python forum</a>
</div>
style.css:
body { 
  background: #67B26F;  
  background: -webkit-linear-gradient(to right, #4ca2cd, #67B26F);
  background: linear-gradient(to right, #4ca2cd, #67B26F);
  font-size: 100%;
  padding:0; 
  margin:0;		
}

html {
  height: 100%
}
Now from command line in folder where app.py is.
Run python app.py.
Then it look like this:
E:\all_flask\my_app
λ python app.py
 * Serving Flask app "app" (lazy loading)
 * Environment: production
   WARNING: Do not use the development server in a production environment.
   Use a production WSGI server instead.
 * Debug mode: on
 * Restarting with stat
 * Debugger is active!
 * Debugger PIN: 334-187-997
 * Running on http://127.0.0.1:5000/ (Press CTRL+C to quit)
See address copy that to browser http://127.0.0.1:5000/.
Then should show the page and with a link to about page.

So can to all development local to a finish web-app.
Only if want to share with world look for a Python friendly host eg DigitalOcean.
Now leave the local web-server and switch to a production ready web-server like Gunicorn.
