[Tutor] making proigress

[andy surany]

Hi Kirk,

I just tried the logic in question (aliasline.find(listname+':/"')==-1)
and the expression works fine (python 2.2.1). Note that I simply tried
it in python command line using a string variable versus reading a line
in the file.

Being not much more than a newbie myself, you might try the same thing.
Go to your command line and execute the basic logic. Won't take you more
than a minute to write - and you can determine whether this is a 1.5.2
problem or not.

Here is the logic I used:

import string
listname='ok'
a='jjj ok:/" lll'
a.find(listname+':/"') # You get an answer of 4 here
a='jjj kkk'
a.find(listname+':/"') # You get an answer of -1 here
a=''
a.find(listname+':/"') # You get an answer of -1 here

HTH.

Regards,

Andy
