Try this:
if form.get("delete_id","") != "" and form.get("delete_data","") != ""
and...
the "get" method lets you have an optional second argument that gets
returned if the key is not in the dictionary.
Also, am I reading your code right? If I enter some fields but not all,
you print a message that says "Nothing entered." Nothing?
The other thing I'd recommend is stick that long list of fields in a
list, and then do operations on that list:
fields = ['delete_id', 'delete_date', 'delete_purchasetype',
'delete_price', 'delete_comment']
then to see if all those fields are empty:
everything = ""
for field in fields:
everything += form.get(field,"")
if everything == "":
print "Absolutely nothing entered!"
