(Plain text will usually be understood by a browser but will look terrible!) The normal way to build a web app is to create an HTML template file with place holders for the data. Then use Python (or any other server language) to inject the data via some kind of web framework. (Flask and Bottle are two simple Python examples) An alternative technique involves writing the app in JavaScript that executes on the browser. That means creating an HTML file that either contains your app as embedded JavaScript or putting your JavaScript code into a separate file and importing it into the HTML. The latter approach is preferred for industrial sites but the single file approach is OK for small applications. Looking at your code we can remove all the lines that should be in your HTML file: > beef_quantity = 28 ## Set before campaign starts. beef_choice = "" > if beef_choice == 'Quarter_Beef': > new_beef_quantity = beef_quantity - 1 > elif beef_choice == 'Half_Beef': > new_beef_quantity = beef_quantity - 2 > else: > new_beef_quantity = beef_quantity - 4 The setting of the data values into the HTML will depend on your framework. > My end goal (which I still have to figure out) is to have the customer > click on three sections of radio buttons and enter two text fields > which will then display in an alert box where they can click a button That's all HTML function not Python or even JavaScript > to send them to PayPal for payment. Sending to Paypal is a whole new ball game.

Not sure > if this is ALL python or part python and part javascript. It could be either or both. But given your need to send to Paypal I'd suggest you find a framework and work in Python. (Especially since you seem to know some Python) You probably should read the section in my tutorial(or any other) that covers web applications. It's in the last section starting with the topic entitled "Working with the Web" and moving on to "Using Web Application Frameworks" HTH -- Alan G Author of the Learn to Program web site http://www.alan-g.me.uk/ http://www.amazon.com/author/alan_gauld Follow my photo-blog on Flickr at: http://www.flickr.com/photos/alangauldphotos ___ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: https://mail.python.org/mailman/listinfo/tutor

Few (i.e. no) browsers directly support Python. This is why nearly all client-side (running in the brower) web development is done in Javascript. Server-side code can be written in Python, or any other language (Perl and PHP are other common choices) but for code that runs in the browser, it is difficult to use anything but Javascript. But all is not quite lost: http://www.skulpt.org/ https://duckduckgo.com/?q=python+in+the+browser Start by getting a simple "Hello World" type program running in the browser, and then move on to something more ambitious. -- Steve ___ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: https://mail.python.org/mailman/listinfo/tutor
[Tutor] Best way to write this countdown code
Thanks in advance as I've gotten wordy.
I want to integrate the following working code into a website:
beef_quantity = 28 ## Set before campaign starts.
print('Original Beef Quantity: ') ## Displays the wording "Original
Beef Quantity: "
print (beef_quantity) ## Displays the beef quantity before order
beef_choice = 'Quarter_Beef' ## Based on Customer's choice
if beef_choice == 'Quarter_Beef':
print('Quarter Beef selected') ## Notice of beef quantity ordered
print('New Beef Quantity: ') ## Displays the wording "New beef quantity: "
new_beef_quantity = beef_quantity - 1 ## Updates the beef
quantity after order
print(new_beef_quantity) ## Displays the updated beef quantity after order
elif beef_choice == 'Half_Beef':
print('Half Beef selected') ## Notice of beef quantity ordered
print('New Beef Quantity: ') ## Displays the wording "New beef quantity: "
new_beef_quantity = beef_quantity - 2 ## Updates the beef
quantity after order
print(new_beef_quantity) ## Displays the updated beef quantity after order
else:
print('Whole Beef selected') ## Notice of beef quantity ordered
print('New Beef Quantity: ') ## Displays the wording "New beef quantity: "
new_beef_quantity = beef_quantity - 4 ## Updates the beef
quantity after order
print(new_beef_quantity) ## Displays the updated beef quantity after order
I also have two other similar code pieces (delivery.py and locker.py)
that I want to integrate, but I'll put them in other emails.
My end goal (which I still have to figure out) is to have the customer
click on three sections of radio buttons and enter two text fields
which will then display in an alert box where they can click a button
to send them to PayPal for payment. The other part of this is that
the number of available beef will countdown as each order is placed
until zero s available which will then display "Sold Out!" Not sure
if this is ALL python or part python and part javascript.
Again, Thank you.
Joe
