Python + HTML programming website order form

Question

Hi I am working on a school project where I need to make an order form for a website using python and HTML. I am having trouble adding these:

if form.getvalue("interior"):
    print "<p>Interior Painting(s) quantity:", form["quantity"].value, "</p>"
    print "<p>You Cost is :$" ,int(form["quantity"].value)*2, ".00</p>"

else:
        print "<p>Interior Painting(s) ordered: <b>0</b> <br /> Cost: <b>$0</b></p>"

if form.getvalue("exterior"):
    print "<p>Exterior Painting quantity:", form["quantity2"].value, "</p>"
    print "<p>You Cost is :$" ,int(form["quantity2"].value)*1, ".00</p>"

else:
        print "<p>Exterior Painting(s) ordered: <b>0</b> <br /> Cost: <b>$0</b></p>"

if form.getvalue("pressure"):
    print "<p>Pressure Washing quantity:", form["quantity3"].value, "</p>"
    print "<p>You Cost is :$" ,int(form["quantity3"].value)*150, ".00</p>"
else:
       print "<p>Pressure Washings(s)ordered: <b>0</b> <br /> Cost: <b>$0</b></p>"

if form.getvalue("wood"):
    print "<p>Wood Finishing quantity:", form["quantity4"].value, "</p>"
    print "<p>You Cost is $" ,int(form["quantity4"].value)*3, ".00</p>"
else:
        print "<p>Wood Finsihings(s) ordered: <b>0</b> <br /> Cost: <b>$0</b></p>"

if form.getvalue("spraycan"):
    print "<p>Spray Can quantity:", form["quantity5"].value, "</p>"
    print "<p>You Cost is $" ,int(form["quantity5"].value)*10, ".00</p>"
else:
        print "<p>Spray Cans ordered: <b>0</b> <br /> Cost: <b>$0</b></p>"

I am trying to add all the int(form[quantity..1..2].value all together and display a result after these. I have tried assigning the form[quantity].value to a varaible and adding them up but it isnt working. Also since getvalue only executes when the user selects the option, how can i go about doing this? Thanks.

form = cgi.FieldStorage()

This is where it becomes a mess, separate HTML from python, use a template language, like jinja2. — alecxe, Commented Jul 31, 2014 at 2:22
Make HTML templates, put placeholders into it and render the templates with the appropriate context. See Templating. — alecxe, Commented Jul 31, 2014 at 2:28

Here's my take on your question, the logic is to allocate calculated values to variables so you can manipulate them for a sum.

q1 = int(form["quantity"].value)*2
q2 = int(form["quantity2"].value)*1
q3 = int(form["quantity3"].value)*150
q4 = int(form["quantity4"].value)*3
q5 = int(form["quantity5"].value)*10

if form.getvalue("interior"):
    print "<p>Interior Painting(s) quantity:", form["quantity"].value, "</p>"
    print "<p>You Cost is :$" ,q1, ".00</p>"

else:
    q1 = 0
    print "<p>Interior Painting(s) ordered: <b>0</b> <br /> Cost: <b>$0</b></p>"

if form.getvalue("exterior"):
    print "<p>Exterior Painting quantity:", form["quantity2"].value, "</p>"
    print "<p>You Cost is :$" ,q2, ".00</p>"

else:
    q2 = 0
    print "<p>Exterior Painting(s) ordered: <b>0</b> <br /> Cost: <b>$0</b></p>"

if form.getvalue("pressure"):
    print "<p>Pressure Washing quantity:", form["quantity3"].value, "</p>"
    print "<p>You Cost is :$" ,q3, ".00</p>"
else:
    q3 = 0   
    print "<p>Pressure Washings(s)ordered: <b>0</b> <br /> Cost: <b>$0</b></p>"

if form.getvalue("wood"):
    print "<p>Wood Finishing quantity:", form["quantity4"].value, "</p>"
    print "<p>You Cost is $" ,q4, ".00</p>"
else:
    q4 = 0
    print "<p>Wood Finsihings(s) ordered: <b>0</b> <br /> Cost: <b>$0</b></p>"

if form.getvalue("spraycan"):
    print "<p>Spray Can quantity:", form["quantity5"].value, "</p>"
    print "<p>You Cost is $" ,q5, ".00</p>"
else:
    q5 = 0
    print "<p>Spray Cans ordered: <b>0</b> <br /> Cost: <b>$0</b></p>" 

total = q1 + q2 + q3 + q4 + q5
print "<p>Total: ", total, "</p>"
