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

Hi Kumar,
I was replying to your question:

in which you showed a program that had problems. I'm assuming that you
haven't

Re: [Tutor] extracting numbers from a list
hello list
I have coordinates for exons (chunks of sequence). For
instance:
10 - 50 A
10 - 20 B
35 - 50 B
60 - 70 A
60 - 70 B
80 - 100 A
80 - 100 B
(The above coordinates and names are easier than in
dat)
Here my aim

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

I have a simple question to ask tutors:

I want to print

fx = a[0]

look very carefully at variables 'fy' vs. 'last', what

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[index]

look very carefully at variables 'fy' vs. 'last', what you do with
them, and when, and you should be able to figure out your homework
assignment problem.
Hmmm, homework assignment was probably what I was missing

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 thefirst pass of the loop the elements are unchanged, for the remaining we add one.

Note that this changes the original list, which may or may not be
acceptable. Normally you would expect a printing

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[2:]))
