I believe this is the same as
write = sys.stdout.write
though you never use it that I see.
msg_id = 0
f = open( "nul", "w" )
for line in fileinput.input( mode = "rb" ):
I presume you are expecting the line to be undecoded bytes, as with
open(f,'rb'). To be sure, add write(type(line)).
if line.startswith( "From - " ):
msg_id += 1;
f.close()
print( msg_id )
f = open( "msg_{0:0>6}.txt".format( msg_id ), "w+" )
I do not understand why you are writing since you just wanted to look.
In any case, you open in text mode.
else:
f.write( line )
f.close()

It goes ahead and tries to decode to str anyway. Maybe there is a bug,
though maybe the text-mode open in the loop somehow changes fileinput,
especially if you write to something it has open. So I would not report
a bug until I tried reading without writing.
