as I know , agrep can handle this , at least the newer version from http://www.tgries.de/agrep/index.html with a -f property. here is a agrep port to python http://www.bio.cam.ac.uk/~mw263/pyagrep.html, but it is some out of date, and in it's discription "matching of multiple input patterns is def

list to tuple

Hi, I got several dynamic lists a1, b1, c1, from a python application such as a1 = [1,5,3,2,5,...], the len(a1) varies. Same to b1, c1, With python, I would like to reorganize them into a tuple like t1 = ((a1[0],b1[0],c1[0],...),(a1[1],b1[1],c1[1],...),...) Anybody knows

constructing bytestrings

I use 's = os.read(fd, 12)' to grab 12 bytes from a file. Now, I want to create a string, s1, which contains 16-12=4 bytes: 4,0,0,0, followed by the contents of s. I know how to 's1 = "\x04\x00\x00\x00"' and how to 's3 = s1+s', but I don't know how to construct s1 dynamically (i.e., given N, cons
