Lists in Python -
i noticed can multiply list scalar behavior weird if multiply: [2,3,4] * 3 i get: [2,3,4,2,3,4,2,3,4 ] understand results it's for? there other weird operations that? the main purpose of operand initialisation. example, if want initialize list 20 equal numbers can using loop: arr=[] in range(20): arr.append(3) an alternative way using operator: arr = [3] * 20 more weird , normal list operation on lists can find here http://www.discoversdk.com/knowledge-base/using-lists-in-python
