Python：在请求用户输入inpu之间关闭console/shell中的自动输出

Question

当我运行下面的代码时，我经常被在用户输入之间打印的大量对象创建确认信息所困扰。。。我想如果有什么办法，我可以沉默的控制台，而用户专注于输入答案。我已经找到了一些粗略的解决方案，但它们似乎太复杂了，不适合这个问题有多简单。下面是代码片段和示例输出。谢谢！你知道吗

代码：

#Engages in battles until user quits
def battle(self):

    battles_threshold = min([a.battles_fought for a in self.artists])
    contenders = [a for a in self.artists if
        a.battles_fought == battles_threshold]
    noncontenders = list(set(self.artists)-set(contenders))
    print(noncontenders)
    contenders.append(random.choice(contenders))
    contender1=contenders.pop(random.choice(range(len(contenders))))
    contender2=contenders.pop(random.choice(range(len(contenders))))
    elo1 = contender1.elo
    elo2 = contender2.elo
    outcome = ''
    while (outcome != 'y' and outcome != 'n' and 
        outcome != 'm' and outcome != 'q'):
        outcome = \
        raw_input('Do you like "' + contender1.name +
            '" more than "' + contender2.name + '"?\n')
    if outcome == 'q':
        return None
    elif outcome == 'y':
        contender1.elo_calc(1,contender2.name,elo2)
        contender2.elo_calc(0,contender1.name,elo1)
    elif outcome == 'n':
        contender1.elo_calc(0,contender2.name,elo2)
        contender2.elo_calc(1,contender1.name,elo1)
    else:
        contender1.elo_calc(0.5,contender2.name,elo2)
        contender2.elo_calc(0.5,contender1.name,elo1)
    pickle.dump(music_battler, open(self.path_name +
        'music_battler.p','wb'))
    self.battle()

输出：

Answer 1

print(noncontenders)是给您打印输出的行[<__main__.Artist instance at 0x10dc91ab8>, <__main__.Artist instance at...删除它应该消除这一点。你知道吗
