This has as advantage (or disadvantage) that you can set the variable at the CLI and see the output the browser could get. -- John Bokma j3b Hacking & Hiking in Mexico - http://johnbokma.com/ http://castleamber.com/ - Perl & Python Development -- http://mail.python.org/mailman/listinfo/python-list

It provides you with a text console interface but can also provide HTML.

OK, this works in Python 2:
#!/usr/bin/python
import sys, os
if __name__=="__main__":
if os.isatty(sys.stdout.fileno()):
print "Terminal"
else:
print "Content-type:text/html\n\nBROWSER"
likewise in Python3:
#!/usr/local/bin/python3.1
import sys, os
if __name__=="__main__":
if os.isatty(sys.stdout.fileno()):
print("Terminal")
else:
print("Content-type:text/html\n\nBROWSER")
Thank you, always impressed with the fast help here.

I can only guess you mean as cgi or mod_python-skript? However, maybe if os.isatty(sys.stdout.fileno()): works for you. Or you could check for certain environment variables that are present when running as CGI or mod_python skript, but not knowing *what* you do can only lead to educated guesses at best.

Recall that issubclass(bool, int) is true and that True == 1 in Python due to details of said subclassing. Note also that "== True" is almost always unnecessary as it is essentially implicit in the "if". I suspect you instead meant to write: if len(sys.argv) > 0: which for the record can be written more idiomatically as: if sys.argv: # bool(some_list) is True if some_list is not empty Which, however, as I explained, is always true since argv is /never/ completely empty, and thus the test is useless. What you probably *wanted* is: if len(sys.argv) > 1: Which is effectively the opposite of my very first code snippet and checks whether we /were/ passed some arguments on the command line. > and it seemed to work. By happy accident I suspect, due to the aforementioned way == works between bools and ints and probably a logic error in your code. > Py3 must have broken that by sending a list > with the path to the script in BOTH the browser and Terminal. Is there > some newfangled way to determine what is running the script (hopefully > without a try wrapper)? How exactly are you running the script *"in"* the browser? Browsers can only execute JavaScript, not Python. Do you mean you're running it via a webserver? If so, there are /several/ possible ways of doing that, please explain exactly which you are using.

Py3: Terminal or browser output?
Hello, searched all over but no success. I want to have a script output HTML if run in a browser and plain text if run in a Terminal. In Python 2, I just said this: if len(sys.argv)==True: and it seemed to work. Py3 must have broken that by sending a list with the path to the script in BOTH the browser and Terminal. Is there some newfangled way to determine what is running the script (hopefully without a try wrapper)? -- Gnarlie -- http://mail.python.org/mailman/listinfo/python-list
