Arrays being re-assigned (Python) : <p>I'm recreating Conway's game of life in pygame, and I've been having an issue implementing the preset feature. When I'm assigning the preset array to the default array, and then assigning it back to the default array again, the preset is changed. I'm only editing the array "Initial_frame" but it is somehow changing the preset array.</p>
