(Side point: Please don't top-post. The convention on this mailing list, and most other technical mailing lists, is what's sometimes called "interleaved style"; you trim the quoted text to what's needed for context, and put your text underneath what you're referring to. See https://en.wikipedia.org/wiki/Posting_style#Interleaved_style for more info.) >>> 1073741877&60 52 >>> bin(52) '0b110100' Everything I've written with the triple-angle-bracket marker can be typed in at the Python prompt, and you'll see exactly what it does. In this case, you can see that you're absolutely right: 1073741877 has 1101 in those positions, so if you're looking for 1011, it won't match: >>> 0b101100 44 However, 1073741869 would: >>> 1073741869&60 44 The way to test would be something like this: >>> (1073741877 & 0b111100) == 0b101100 False >>> (1073741869 & 0b111100) == 0b101100 True ChrisA -- https://mail.python.org/mailman/listinfo/python-list
