No, struct converts your data into a string of bytes and provides a way to view a string representation of those bytes. But you can use bitmasks to get at the individual bits. (See my Using the OS topic for a box on bitwise operators and use of bitmasks.) Basically you want to bitwise AND the data with a mask containing just a one in the 8th position (since 1& 0 = 0 and 1& 1 = 1) Thus 10000000 = 80 hex. So: >>> for n in range(125,130): ... print n,':',n&0x80 ... 125 : 0 126 : 0 127 : 0 128 : 128 <--- the one is set so the & returns the mask 129 : 128 >>> > so that I get 8 binary bits as a string? See the bin() function in the sidebar in my topic for a function to display a number in its binary form. -- Alan Gauld Author of the Learn to Program web site http://www.freenetpages.co.uk/hp/alan.gauld _______________________________________________ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor
