>>> print "0x%0X" % 12345 0x3039 >>> print "0x%0.X" % 12345 0x3039 >>> print "0x%1X" % 12345 0x3039 >>> print "0x%10X" % 12345 0x 3039 >>> print "0x%2X" % 12345 0x3039 >>> print "0x%3X" % 12345 0x3039 >>> print "0x%0.10X" % 12345 0x0000003039 >>> print "0x%0.5X" % 12345 0x03039 >>> print "0x%0.5X" % 123456 0x1E240 >>> print "0x%0X" % 123456 0x1E240 >>> print "0x%0.5X" % 2222 0x008AE >>> print "0x%0.5X" % 22222 0x056CE >>> print "0x%0.5X" % 122222 0x1DD6E Ok, so the character after the % and before the . is the padding character, and the number after the . and before the X is the minimum size for the string to be. So print "0x%0.5X" % 12345 seems to do what you want. -- Email: singingxduck AT gmail DOT com AIM: singingxduck Programming Python for the fun of it. _______________________________________________ Tutor maillist - [EMAIL PROTECTED] http://mail.python.org/mailman/listinfo/tutor
