It doesn't *behave* like a list. It **IS** a list. I know that people
have already pointed you to the documentation, where getvalue is
documented to return either a string or a list, depending on how many
values there are in the form.
So, yet again, here is the documentation:
http://docs.python.org/3/library/cgi.html
READ IT.
Here is an extract:
[quote]
In the previous section, you learned to write following code anytime you
expected a user to post more than one value under one name:
item = form.getvalue("item")
if isinstance(item, list):
# The user is requesting more than one item.
else:
# The user is requesting only one item.
[end quote]
Read the rest of the docs. Don't ask any more questions until you have
read them. Then, if anything is still unclear, you can point to a section
of the docs and say "I don't understand this".

Re: Receing a form variable as a list instead of as a string
if page or form.getvalue('show') == 'log':
# it is a python script
page = page.replace( '/home/nikos/public_html/cgi-bin', '' )
elif page or form.getvalue('show') == 'stats':
page = page.replace( '/home/nikos/public_html/cgi-bin', '' )
in the first if option page works a string and replace happens , while in the
second it behaves liek a list and the error i mentioned is being produced.

Ulrich even *told* you what to do: "convert it to a string yourself" Do you do that in your code? No. Instead, you assign a value _to the same label_ and expect it to do magic.

No. You're simply _not_ thinking about what you're doing.

What do you think "page = page" is doing? Hint: you could replace
those lines with 'pass' and your code would work _exactly the same_.

Re: Receing a form variable as a list instead of as a string
But if i write it as:
if not page and os.path.exists( file ):
# it is an html template
page = file.replace( '/home/nikos/public_html/', '' )
elif page or form.getvalue('show') == 'log':
# it is a python script
page = page
elif page or form.getvalue('show') == 'stats':
page = file.replace( '/home/nikos/public_html/', '' )
==
I get the error that i cannot use 'replac'e to a 'list'.
How can i avoid that?

i manages to work around it by using this:
Indeed as Andreas said i was overusing the form variable 'page'
file = form.getvalue('file') # this comes from .htaccess
page = form.getvalue('page') # this comes form metrites.py or index.html
if not page and os.path.exists( file ):
# it is an html template
page = file.replace( '/home/nikos/public_html/', '' )
elif page or form.getvalue('show'):
# it is a python script
page = page
else:
#when everything else fails default
page = page

Maybe because it is a list? Try e.g. "print(type(page))" or "print(page)" to gain some insight. How to receive that form variable as a string? For that, you'd have to adjust the code that you received it from. If that's not possible, convert it to a string yourself. But didn't you want a "form variable"?
