I took a quick look into the cgi module, and FieldStorage class doesn't seem
to have a getvalues attribute. You should get an exception rather than a
None value. For easier debugging make sure your script starts with the lines
#!/usr/bin/env python3
import cgitb
cgitb.enable()

Remove as much as you can from your script. E. g., does the following script
show the contents of the form when you replace your current Hello.py with
it?
#!/usr/bin/env python3
import cgitb
cgitb.enable()
import cgi
import sys
sys.stdout.write("Content-type: text/html\r\n\r\n")
print("""<html><body>""")
try:
form = cgi.FieldStorage()
cgi.print_form(form)
except:
cgi.print_exception()
print("""</body></html>""")
If it doesn't double-check your setup (is the script executable, is your
server configured properly etc.); once the basics work put stuff back in
until the code does what you want -- or breaks. Then you can at least point
to the exact statement that causes the breakage.
