It rather depends on what you are doing with the data. Python ultimately will
have to make exactly the same calls to the open and read functions that C does
and as such it can be no faster than the system calls. If you are doing anything
special with the data then perhaps Python can help with that to speed things up.
If your C program has a good algorithm to extract the data from the binary file
then you are probably going to use much the same algorithm in Python, however
Python may help with the data structures and how you process the data after you
read it in.
