seach for pattern based on string

[richie05 bal]

i am starting to learn python and I am stuck with query I want to
generate with python
File looks something like this
TRACE: AddNewBookD {bookId 20, noofBooks 6576, authorId 41,
publishingCompanyId 7}
TRACE: AddNewBookD {bookId 21, noofBooks 6577, authorId 42,
publishingCompanyId 8}

I want to first search for AddNewBookD
if found
store bookId, noofBooks, authorId and publishingCompanyId

I know how to search for only AddNewBookD or find the pattern bookId
20, noofBooks 6576, authorId 41, publishingCompanyId 7 but I don't
know how search one based on another.

Using a regular expression I would perform a match against each line.
If the match fails, it will return None. If the match succeeds it
returns a match object with which you can extract the values

So your code to store the result would be inside an if m: block

('20', '6576', '41', '7')
