- throwawaymaths 3y agoPython lists are generally not contiguously allocated memory (I think it might be if you are storing integers less than 255), don't be fooled. That's why you need numpy.
- peoplefromibiza 3y agoI'm talking about Python arrays https://docs.python.org/3/library/array.html https://docs.python.org/3/library/array.html >>> a = array('B', [1, 2, 3, 4, 5]) >>> str(a.buffer_info()[1] * a.itemsize) + " bytes at address #" + str(a.buffer_info()[0]) '5 bytes at address #4379640336' >>> b = array('l', [1, 2, 3, 4, 5]) >>> str(b.buffer_info()[1] * b.itemsize) + " bytes at address #" + str(b.buffer_info()[0]) '40 bytes at address #4380812752'
