@bvdet
I thought it was interesting to provide another tip on how create a dict from a list (given the list be the values).

Your solution is perfectly right.

To get the same answer, I'll do:

Code:

>>> d = dict(zip(set(s2ID),  map(lambda x: s2ID.count(x), set(s2ID))))
>>> print d
{'a02': 3, 'a03': 4, 'a01': 1}

Actually, I don't use list.setdefault () because I never...

The very basics of lists:

Code:

>>> my = my.split()
>>> print (' '.join(my[:-1]), my[-1])
('my name is', 'david')

Also:

Code:

>>> import operator
>>> keys, d = range(len(s2ID)), {}
>>> map(operator.setitem, [d]*len(keys), keys, s2ID)
>>> print d
{0: 'a01', 1: 'a02', 2: 'a02', 3: 'a02', 4: 'a03', 5: 'a03', 6: 'a03', 7: 'a03'}

python is not PHP: there is no variable variables.

Normally, the data should be a dictionary saved using pickle. You should not do import hundreds/thousands of lists/tuples.

Here's a solution. I wrote your data as they are (very badly formatted) in an external file.

data.txt:
A = ['a', 'b', 'c']
B = ['d', 'e', 'f']
...

Code:

import re
f = open('data.txt', 'r')

...

You should install a PDF printer driver (such as PDF Creator) and produce your PDF directly from Excel. This is so basic nowadays...
