I publish the following Modul with Bobo:
Very simple:
hello.py:
import sys, os, time
import DocumentTemplate
lib=sys.path[0]
sys.path.append(os.path.join(lib,'DT'))
def hello():
    "Display a greeting"
    # print "rrr"
    X3 = DocumentTemplate.HTMLFile(lib+'/hello.dtml')
    return X3()
...
Now, when I make the commentated line  print "rrr"  active, I get
  Internal Server Error
The "print" goes directly to the webserver, which confused it: it expects
HTTP headers like "HTTP/1.0 200 Okay".

The "return" sends your data to *Zope*, which then does the header stuff
for you.  Same with cookies, content-type, etc.

Summary: dont use 'print', or redirect stdout to a log file.
