7.1. Python scripts
Python scripts run with Karrigell are ordinary Python scripts, except that
the print
statement sends the output to the client's browser
instead of the console window. Therefore you'll have to write HTML code if
you need the correct formatting ; for a minimal table you'll have to write
something like
print "<TABLE>" print "<TR>" print "<TD>Name</TD>" print "<TD>Address</TD>" print "</TR>" print "</TABLE>"
or, using the multi-line Python syntax :
print """<TABLE> <TR> <TD>Name</TD> <TD>Address</TD> </TR> </TABLE>"""
from HTMLTags import * print TABLE(TR(TD("Name")+TD("Address")))
If you write Python scripts that musn't be executed by Karrigell (for instance because they have a GUI-based interaction with the user) you can include this code at the top of your script :
try: SCRIPT_END except NameError: pass else: print "This script can't be executed by Karrigell" raise SCRIPT_END (... rest of your script here ...)
Since SCRIPT_END
is in the namespace of Python scripts when executed in
Karrigell, the execution stops in this case ; when run from the command line, a
NameError
is raised, and is ignored by the script
