My apologies. The good news is that makes the solution even easier.

OPS! This code now produces desired results. I suppose that this works for
smaller blocks. For larger blocks, it might be cumbersome. EK
b=[12, 20, 35]

for i in range(len(b)):
 if i==0:
  c=0
 elif i==2:
  c=24
 else:
  c=b[i-1]
 for j in range(c, b[i]):
 print(i+1,j+1)

The problem here is that it doesn't give the gaps in the output
data that the OP requested. That's why we said they need the start
and stop values in the ranges.

If you want to go a little further, you can use zip and enumerate.

py> stops = [3, 5, 9]
py> starts = [0] + stops[:-1]
py> for i, (start, stop) in enumerate(zip(starts, stops)):
... for j in range(start, stop):
... print(i, j)

Here is a beginner code that might work for you. Best of luck.   EK

b=[12, 20, 35]

for i in range(len(b)):
 if i==0:
  c=0
 else:
  c=b[i-1]
 for j in range(c, b[i]):
  print(i+1,j+1)

Re: [Tutor] Loop in pre-defined blocks

[Jignesh Sutar]

Sorry, to be a little bit more descriptive. I'd like to loop from 1 to 35
but within this loop there are divisions which I need to prefix that
particular division number.

My output would look like this:

1 1
1 2
1 3
1 4
1 5
1 6
1 7
1 8
1 9
1 10
1 11
1 12
2 13
2 14
2 15
2 16
2 17
2 18
2 19
2 20
3 25
3 26
3 27
3 28
3 29
3 30
3 31
3 32
3 33
3 34
3 35

Can you explain in English what you are trying to do.
Working through your algorithm in my head is too much
like hard work. At the very least show us the output.

Better still explain what it means - what the data
represents and how the outputs relate to the inputs.

[Tutor] Loop in pre-defined blocks

[Jignesh Sutar]

Is there a better way to code the below than to specify blocks as I have.
Ideally I'd like to specify blocks simply as *blocks=(12,20,35)*

blocks=[(1,12), (13,20), (25,35)]
for i,j in enumerate(blocks):
for x in xrange(blocks[i][0],blocks[i][1]+1):
print i+1, x


Thanks in advance.
Jignesh
