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, construct "N" followed by N-1 "0", where "N" and "0" are single byte values with N<16). How do I do this? -- http://mail.python.org/mailman/listinfo/python-list
