Question

Using Python, I’m trying to print out a table, with collated information based on a set of data like this.

Data 1 - 'Car', 'Cadillac','Blue'

Data 2 - 'Car', 'Aston Martin','Black'

Data 3 - 'Car', 'Cadillac', 'Blue'

Now I need to find the number of times the same combination occurs – i.e. I would like to print that the combination of 'Car', 'Cadillac' and 'Blue' occurs twice, and the other, once. How do I do this in Python?

EDIT: I’m using Python 2.4!

Answer 1

First tuple the string and put it all in a list; then use count

>>> list
[('Car', 'Cadillac','Blue'), ('Car', 'Aston Martin','Black'), ('Car', 'Cadillac', 'Blue'), ...]
>>> list.count(('Car', 'Cadillac', 'Blue'))
