userid = form["userid"].value

for entry in data:
if userid != entry[0]:
print "<p> No grades available. </p>"
else:
print


entry[0] = [studenta, studentb, studentc, etc...]
entry[1] = [75,80,90, etc...]

I'm trying to create a web form where a user can type in their userid (studenta) and then the program will only display their own information. For example, studenta:75. However, if the username is not on file, it displays "No grades available".

Can anyone give me a hand?

A dictionary and dictionary method get() are well suited for this task. Example:

ids = ['studenta', 'studentb', 'studentc']
infoList = [75,80,90]

dd = dict(zip(ids,infoList))
print dd

for id in ['studenta', 'studentb', 'studentc', 'studentd']:
    info = dd.get(id, "No information is available")
    print "Information for student %s: %s" % (id, info)

Output:

>>> {'studentc': 90, 'studentb': 80, 'studenta': 75}
Information for student studenta: 75
Information for student studentb: 80
Information for student studentc: 90
Information for student studentd: No information is available
