i need replace few bytes in asn1 encoded binary file. because of i'm out of asn1 scope, want replace bytes starting @ position 9 (offset) , of length 9 bytes. i able open file binary write fh = open("emvdata_3839_test.der", "r+b") fh.seek(8) fh.write(bytearray(9)) fh.close() this replace 9 bytes 00 00 00 .... i need convert number e.g. 123456789012345678 \x00\x01\x02\x03\x04\x05\x06\x07\x08\x09\x00\x01... can put fh.write() method , replace old values new. split long number single digits, convert them format \xyy , make bytearray ? ( mean format file.write() can handle) please consider in python cannot write basic loop without googling :) thanks much
