Dear group,

 I have two tables:

First table: spot_cor:
432     117
499     631
10      0
326     83
62      197
0       0
37      551



Second table: spot_int
0       0       98
1       0       5470
2       0       113
3       0       5240
4       0       82.5
5       0       92
6       0       5012
7       0       111
8       0       4612
9       0       115
10      0       4676.5



I stored these two tables as lists:

>>> spot_cor[0:5]
['432\t117', '499\t631', 10\t0', '326\t83', '62\t197']

Note there is no ' before the 10. That won't fly'

>>> spot_int[0:5]
['  0\t  0\t18.9', '  1\t  0\t649.4', '  10\t
0\t37.3', '  3\t  0\t901.6', '  4\t  0\t14.9']

It would be a lot easier to work with if the lists looked like (assumes all data are numeric):
[(432,117), (499,631), (10,0), (326,83), (62,197)]
[(0,0,18.9), (1,0,649.4), (10,0,37.3), (3,0,901.6), (4,0,14.9)]


What is the source for this data? Is it a tab-delimited file? If so the CSV module can help make this translation.

I also assume that you want the first 2 elements of a spot_int element to match a spot_cor element.

Then (for the subset of data you've provided):

>>> for ele1 in spot_cor:
...       for ele2 in spot_int:
...             if ele1 == ele2[:2]:
...                     print "%8s %8s %8s" % ele2
...
      10        0     37.3

I want to write all the three columns of spot_int.

Hope that helps.
