python - 当列表不包含 if 语句指定的条件时，为什么会触发这个 if 语句？

问题描述

为什么触发第一个 if 语句而不是它之后的 elif 语句？

player_moves = [1, 3, 4]
computer_moves = [5, 2]
if 4 and 5 in computer_moves and 6 not in player_moves:
    computer_moves.append(6)
    print("Computer chooses " + str(computer_moves[-1]))
elif 2 and 5 in computer_moves and 8 not in player_moves:
    computer_moves.append(8)
    print("Computer chooses " + str(computer_moves[-1]))
