I have written a small script taking the output of a form, formating it and displaying it in a browser. When I run it I get a 500 error with
Error message:
End of script output before headers: certificate.py
It is similar to an even simpler script which works fine. As far as I can see I am outputing the headers first.
This is my script:
#!/Users/User/AppData/Local/Programs/Python/Python36-32/python
print("Content-type:text/html\r\n")
# Import modules for CGI handling
import cgi, cgitb
# Create instance of FieldStorage
form = cgi.FieldStorage()
# Get data from form fields
# text fields
tname = form.getvalue('tname')
tdate = form.getvalue('tdate')
# textarea
comments = form.getvalue('comments', 'None')
# checkboxes
checkbox1 = ['yes', 'no'][not form.getvalue('certificate')]
checkbox2 = ['yes', 'no'][not form.getvalue('alumni')]
# radio button
grade = form.getvalue('grade', 'Not set')
# dropdown
subject = form.getvalue('subject', 'Not entered')
aoran = ['a', 'an'][grade[0] in 'aeiou']
if ( grade != "ordinary" ):
grade = grade + ' class honours'
print('''\

<h1>Certificate</h1>
<h2>This is to certify that</h2>''')
print("<h3> %s </h3>" % (tname))
print("<p>has been awarded</p>")
print("<p> %s %s degree</p>" % (aoran, grade))
print("<p>in %s </p>" % (subject))
print("<p>Date: %s </p>" % (tdate))
print("<p>Comments: %s </p>" % (comments))
print("<p>--- for official use ---<br>"
print("certificate: %s; alumni: %s </p>" % (checkbox1, checkbox2))
print('''\
</div>
</body>
</html>''')
Any ideas where I’m going wrong?
Edit: Okay, it was due to a syntax error. I guess the syntax error would have been output before the headers but I didn’t get to see it!
