Ok, well then something is still wrong because I'm still getting syntax
errors that I can't figure out. Is there a python tutorial that is
more like cgi101.com (only python)? (Ie. including source codes, live
working examples, and different sections for different commands)
Btw, here is the code again:
#!/usr/bin/env python
import cgi
print "Content-type: text/html\n\n"
form = cgi.FieldStorage()
c = form['c'].value
except KeyError :
c = ""
content = c
if c == 'abc':
content = "abc123"
elif c == 'def':
content = "def456"
else:
print "error: content failed\n"
file = open("text.txt")
text = file.read()
file.close()
print """
%(content)s
<br> <br> <br>
%(text)s
""" % vars()
It says there is an error near except KeyError: but I've never used
python before so I don't know what to change.
Thanks,
Kyle
