類型錯誤：對於不支持+操作數類型（S）：「詮釋」和「海峽」錯誤

Question

林和我的代碼有問題，它說

TypeError: unsupported operand type(s) for +: 'int' and 'str'

，我不知道爲什麼。我的代碼導致這個區域如下所示，所有幫助將不勝感激：D！*編輯錯誤似乎發生，因爲輸入選項，如果這有助於任何方式。

Score1 = str(input("what did the first person get in their test the first  time?")) 
Score2 = str(input("what did the first person get in their test the second time?")) 
Score3 = str(input("what did the first person get in their test the third time?")) 

Score4 = str(input("what did the second person get in their test the first time?")) 
Score5 = str(input("what did the second person get in their test the second time?")) 
Score6 = str(input("what did the second person get in their test the third time?")) 


Score7 = str(input("what did the third person get in their test the first time?")) 
Score8 = str(input("what did the third person get in their test the second time?")) 
Score9 = str(input("what did the third person get in their test the third time?")) 


P1S = [Score1, Score2, Score3] 
P2S = [Score4, Score5, Score6] 
P3S = [Score7, Score8, Score9] 



print ("here are the scores of",Name1,",well done") # defines scores 
print(P1S) 
print ("here is the average score of",Name1,",Well Done") # makes average of scores 
print(sum(P1S)/float(len(P1S))) 

print ("here are the scores of",Name2,",well done") # defines scores 
print(P2S) 
print ("here is the average score of",Name2,",Well Done") # makes average of scores 
print(sum(P2S)/float(len(P2S))) 

print ("here are the scores of",Name3,",well done") # defines scores 
print(P3S) 
print ("here is the average score of",Name3,",Well Done") # makes average of scores 
print(sum(P3S)/float(len(P3S))) 

Answer 1

您明確地要小心，事情該用戶的輸入字符串：

Score1 = str(input("what did the first person get in their test the first  time?")) 

如果通過int()或float()（取決於你所期望的輸入來定）更換str()，你問題應該消失，因爲你會得到一個數字類型而不是str ing。

Answer 2

演員串默認輸入到一個整數，這樣就可以計算出平均分：

Score1 = int(input("what did the first person get in their test the first time?")) 

Answer 3

您還可以使用地圖在計算自己的分數。

print ("here are the scores of",Name1,",well done") # defines scores 
print(P1S) 
print ("here is the average score of",Name1,",Well Done") # makes average of scores 
print(sum(map(int,P1S))/float(len(P1S))) 

print ("here are the scores of",Name2,",well done") # defines scores 
print(P2S) 
print ("here is the average score of",Name2,",Well Done") # makes average of scores 
print(sum(map(int,P2S))/float(len(P2S))) 

print ("here are the scores of",Name3,",well done") # defines scores 
print(P3S) 
print ("here is the average score of",Name3,",Well Done") # makes average of scores 
print(sum(map(int,P3S))/float(len(P3S)))
