Hi Kumar,

Thank you Danny. I am going over your email and trying
to understand (i am a biologist with bioinformatics
training).
I am not sure if I got your opinion about the way I
solved. do you mean that there is something wrong with
the way i solved it.
I am not sure If I explained the problem correctl

Hi Kumar,
If you're concerned about correctness, I'd recommend that you try thinking
about the problem inductively. An inductive definition for what you're
asking is st

Re: [Tutor] extracting numbers from a list
hello list
I have coordinates for exons (chunks of sequence). For

As long as we're all taking turns, what about a functional approach:
>>> a = [10, 15, 18, 20, 25, 30, 40]
>>> def pairs(lst):
... return list.__add__([(lst[0], lst[1])], zip(map((1).__add__,
lst[1:]), lst
I agree.

Note that this changes the original list, which may or may not be
acceptable. Normally you would expect a p
My solution : (i have tested it)
list1 = [10,15,18,20,25,30,40]
for i in range(len(list1)-1): print list1[i],list1[i+1] list1[i+1] += 1
Note:
# print the consecutive elements; for the first pass of the loop the elements are unchanged, for the remaining we add one.

The simplest solution would seem to be a while loop:
print a[0], a[1] # special case
index = 1
while index < len(a):
print a[index-1]+1, a[
