Python：關閉控制檯/ shell中的自動輸出，讓用戶輸入時詢問用戶輸入

Question

當我運行下面的代碼時，我經常受到用戶輸入之間打印的對象創建確認的負載的影響......如果有某種方式可以在用戶專注於輸入答案的同時使控制檯保持沉默。我找到了一些粗略的解決方案，但它們看起來太過複雜，因爲問題的簡單程度如何。下面的代碼片段和示例輸出。謝謝！

代碼：

#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()

Do you like "alesso" more than "taking back sunday"? 

Answer 1

print(noncontenders)是給你刪除它應該消除打印輸出[<__main__.Artist instance at 0x10dc91ab8>, <__main__.Artist instance at...行。
