coding request

[Marxon]

Hi all,

is there some bored python coder out there who would code me a small tool?
It should load fileA and fileB
Replace the 1st byte of fileA with the 1st byte of fileB
Replace the 3rd byte of fileA with the 2nd byte of fileB
Replace the 5th byte of fileA with the 3rd byte of fileB
Replace the 7th byte of fileA with the 4th byte of fileB
Repeat this until end of fileB
Save fileA

Thanks a lot
