I would check 3 words at the starting of a line
s=['foo','bar','qwe']
if ln.startswith(s): (this is bad)
what is the best way for making it?
if max(map(ln.startswith,s)):
or
reduce(lambda m,n:m or n, map(ln.startswith, s))
Thanks!

Hi Jonas,
Just checking: is this similar to a question brought up a few days ago?

Iterations over a list of this nature are most succinctly done using list
comprehensions.

Sorry Jonas,
I don't understand what you are trying to do at all.
The subject line and your code snippets don't seem
to match up.

In that case this is the simplest approach:
>> for st in s:
>> if line.startswith(st): do something
That means that if you are reading the lines from a file you'd need a
neted loop:
for line in someFile:
for subst
