Hi all,
I am a Python convert coming from a JavaScript background (as you can probably
tell) and am currently writing my first application using Python which will be
a calculator for an online game I used to play (thought it would be a decent
first project) but am not sure on the syntax for referencing an HTML form input
field, I tried this (which returns an error) -
XHTML form -
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd";>
<html xmlns="http://www.w3.org/1999/xhtml"; xml:lang="en" lang="en">
<head>
<title>DopeWars Junkie Calculator</title>
</head>
<body>
<center>
<form method="post" action="http://newspyn.com/cgi-bin/JunkieCalc.py";>
<p><b>Coat Size:</b> <input type="text" name="coatSize">
<p><b>Used Pockets:</b> <input type="text" name="usedPockets">
<p><b>Lab Space:</b> <input type="text" name="labSpace">
<p><b>Total Junkies:</b> <input type="text" name="totalJunkies">
<p><b>Dealer Visits Remaining:</b> <input type="text" name="DVR">
<p><input type="submit" value="Submit">
</form>
</body>
</html>
junkieCalc.py -
#!/usr/bin/env python
import cgi
def main():
print "Content-type: text/html\n"
form = cgi.FieldStorage()
if form.has_key("coatSize") and form.has_key("usedPockets") and
form.has_key("labSpace") and form.has_key("totalJunkies") and
form.has_key("DVR") and form["coatSize"].value != "" and
form["usedPockets"].value != "" and form["labSpace"].value != "" and
form["totalJunkies"].value != "" and form["DVR"].value != "":
Tokens = 0
while usedPockets > (totalJunkies - labSpace) * 17:
Tokens = Tokens + 1
usedPockets = (usedPockets - totalJunkies + labSpace) * 17
totalJunkies = totalJunkies + 1
print "Tokens"
else:
print "Try again"
main()
This is the error i'm getting -
Traceback (most recent call last): File
"D:\inetpub\vhosts\newspyn.com\cgi-bin\JunkieCalc.py", line 23, in ? main()
File "D:\inetpub\vhosts\newspyn.com\cgi-bin\JunkieCalc.py", line 10, in main
while usedPockets > (totalJunkies - labSpace) * 17: UnboundLocalError: local
variable 'usedPockets' referenced before assignment
Thanks in advance for any help :)_______________________________________________
