Binary file splitting

[l0ngb1t]

been working on a small project for a university course where i needed to split a binary file into blocks for some reasons, i could have use DSplit but i thought why not take advantage of it to practice some python and add something cool to the project paper.

here is the code, it prompts for the file name and the size of the block you want, then it split it for you.

Code: Select all

import os

file_name        = raw_input("enter the full file name  --> ")
block_size       = int(raw_input("enter the block size in bytes  --> "))
statinfo         = os.stat(file_name)
number_of_blocks = statinfo.st_size/block_size
left_over        = statinfo.st_size%block_size
fp               = open(file_name,"rb")

for i in range(0,number_of_blocks):
    block   = fp.read(block_size)
    binfile = open("bin.data."+str(i),"wb")
    binfile.write(block)
    binfile.close()

if left_over:
    block = fp.read(left_over)
    binfile = open("bin.data."+str(number_of_blocks),"wb")
    binfile.write(block)
    binfile.close()

fp.close()

well done! and clean well structured code!
