Title
Body
I find particularly difficult reading binary file with Python. Can you give me a hand? I need to read this file, which in Fortran 90 is easily read by int*4 n_particles, n_groups real*4 group_id(n_particles) read (*) n_particles, n_groups read (*) (group_id(j),j=1,n_particles) In detail, the file format is: Bytes 1-4 -- The integer 8. Bytes 5-8 -- The number of particles, N. Bytes 9-12 -- The number of groups. Bytes 13-16 -- The integer 8. Bytes 17-20 -- The integer 4*N. Next many bytes -- The group ID numbers for all the particles. Last 4 bytes -- The integer 4*N. How can I read this with Python? I tried everything but it never worked. Is there any chance I might use a f90 program in python, reading this binary file and then save the data that I need to use?
