Python的得分無效語法不會工作

Question

if score <=30: 
print = "You have scored:" + score + ":(" 

else score > = 31 and < = 60 
print = "You have scored:" + score + ":/" 

elif score < = 61 
print = "You have scored:" + score + ":)" 

我正在Python中的測驗，我需要它，這樣，當比分爲0-30,30-60和60+之間，顯示了不同的消息，雖然我試圖上面的代碼，它一直說無效的語法。

Answer 1

else score > = 31 and score <= 60 

需要是

elif score > = 31 and score <= 60: 

而你需要一個:添加到最後的elif了。而你的打印報告是錯誤的。語法是print 'hello'或print('hello')，具體取決於python版本。你應該看看初學python語法的東西

Answer 2

這是因爲score變量是一個整數，所以你不能像那樣打印它。試試這個，你打印的東西應該放在括號內，而不是「=」。在if語句之後還應該有一個「：」。試試這個：

if score <=30: 
    print("You have scored:" + str(score) + ":(") 

elif score >= 31 and score <= 60: 
    print("You have scored:" + str(score) + ":/") 

elif score <= 61: 
    print("You have scored:" + str(score) + ":)")
