Hello, I would like to create a set of very similar regular expression. In my initial thought, I'd hoped to create a regular expression with a variable inside of it that I could simply pass a string into by defining this variable elsewhere in my module/function/class where I compile the regular expression, thus making for an easy substitution. However, still after JFGI'ing, I still cannot find the syntax to place a variable inside a regular expression in Python. Is such a thing possible, and if so what is the syntax to do it? If this is not possible, what would be the Python way of swapping a small part of the insides of a regexp without having to copy and paste the code to create as many variations as necessary?
To make this more concrete, I think an example is in order. Let's say I have a document like this The Beatles Rubber Soul Track Listings 1. Drive My Car 2. Norwegian Wood (This Bird Has Flown) 3. You Won't See Me 4. Nowhere Man 5. Think for Yourself 6. Word 7. Michelle 8. What Goes On 9. Girl 10. I'm Looking Through You 11. In My Life 12. Wait 13. If I Needed Someone 14. Run for Your Life Original Release Date: December 3, 1965 Number of Discs: 1 Label: Capitol ... and I want to look for tracks that contain 'oo'. Then, maybe later, I want to look for 'ee', or maybe 'ou'. All the regular expressions would start by searching for a digit at the beginning of the line, and they would allow for characters up until the desired two-letter vowel combination, and then search for the two-letter vowel combination. How can I provide for a way to "drop-in" the two-letter combination I want? Thanks very much for your help and assistance in advance. Chris -- http://mail.python.org/mailman/listinfo/python-list
