Hi Dear People,


As really beginner in Python, I tried to write a simple script that
opens a binary file and replace all appearance of some data with another

It doesn't show me any error message, but file is not modified. Can you
help to understand why?


My script is as follows:

from array import array

a = array('H')

f =  file('project_release.a')

a.fromfile( f,100 )


# update the content

for i in a:

   if i == 0xFFFF:

       a[ a.index(i) ] = 0x7777



#update to new file
