| I'm pulling my hair out as to why I get this error:
| 
| For this code: 
| if 1:
|         print "Content-Type: text/html\n\n"
|         print "whatever",
|         oL = ""
|         for key,value in rv.items():
|                 oL = oL + value + "&" + "blah"
|         print "blah",
|         print "=",
|         print oL
| 
| I get this result:
| Traceback (innermost last):
|   File "./update_user.py", line 58, in ?
|     oL = oL + value + "&" + "blah"
| TypeError: illegal argument type for built-in operation
| 
| WHY???  It seems like it maybe trying to add the variables & elements

Looks like the values in rv are not strings.  How is rv defined?

You can use the % operator.  Instead of

    oL = oL + value + "&" + "blah"

you can write

    oL = oL + "%s&blah" % value

The "%s" means that the value of the variable value will be inserted
into the string at that point as a string.

| of the \n, but not the spaces).

Use sys.stdout.write() instead.
