[SciPy-user] stupid python question : for in in range(nlines) :

Hi,

I have a very dum python question here, hopefully someone can answer 
this in no time:

I have a script including lines such as (reading a file with "nlines" 
lines):

##############################
for i in range(nlines) :
    ...
    ...
    while i < nlines :
      ....
      i += 1
      if ... :
        break
#############################

But of course the "while" loop changes the increment "i", but then, when 
the break condition is valid, it returns to the "for" loop and starts 
again with the set of lines WITHOUT taking into account the fact that 
"i" was incremented (so that it should not read these lines AGAIN).

Hope this is clear. Let me know if you have a simple solution (my 
scripting habits are coming from C, hence the way I stupily wrote things 
here...)

Thanks in advance for any help there

Eric
