Thank you for the answers.
I did not realize that taking only "the half of list comprehension"
is a misuse of it. That would mean list comprehension always "claim"
to be assigned to a variable. But why?
if i *had* a function doing any meaningful with the iterated values
by itstelf, why bother with the returned list.
Ex:
ignore = [ add_to_db(x) for x in my_list if x[:4]=='Hans']

Looks at least as nice to me as

for x in my_list:
     if x[:4]=='Hans':
         add_to_db(x)

But there might be reasons one prefers the for loop.

Back to my original desire:
I of course did not request to add a new funciton to
python built ins, I was just asking, if I miss a nice
idea to do the trick :-)

sys.stdout.write has the drawbacks:
- need to import sys, well....
- does no newline automatically, like print
- only handles strings

Again, no real pain all that :-)
