A question about a metacharacter

[igbt]

I am creating a simple script which is using gtk. In this script you
must enter a text, if you do not enter anything or you enter a dot,
the script will be finished. However, if you don't enter anything the
script works but if you enter a dot (.) the script does not work. I
was investigating about it and I think the problem is with the dot
character sss == "." . I was trying the same line with other
metacharacters like *, (, ) ... and I found the same problem. I was
looking for an example where I could see the way I could do it without
any error but I did not find it. Could somebody tell me how can I
solve this error?



sss = entryName.get_text() # The script gets the text
if sss == "" or sss == ".":
gtk.main_quit() #The script finishes


Thanks ; -)

try this.

sss = entryName.get_text()
if not sss.strip() or sss.strip() == '.':
gtk.main_quit()

I wouldn't be suprised if your input is being captured with End-Of-
Line characters which would cause the mis-match.

It does not work. Thanks for your help

However, if you don't enter anything the
script works but if you enter a dot (.) the script does not work.

Have you tried it with other non-metacharacter values?

sss = entryName.get_text()      # The script gets the text
        if sss == "" or sss == ".":
                gtk.main_quit()        #The script finishes

Try adding this:
else:
print sss, type(sss)

Good luck!
