TypeError: type d'opérande non pris en charge (s) pour +: 'int' et 'str' erreur

Question

Im un problème avec mon code et il dit

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

et je ne sais pas pourquoi. la zone de mon code qui provoque ceci est montrée ci-dessous, toute l'aide serait appréciée: D! * Modifier l'erreur semble se produire en raison des options d'entrée, si cela aide de quelque façon.

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

Vous explicitement prendre soin que les choses les entrées utilisateur sont des chaînes:

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

si vous remplacez str() par int() ou float() (selon ce que vous attendez que l'entrée soit), votre le problème devrait disparaître, car vous obtiendriez un type numérique plutôt qu'un str ing.

Answer 2

Cast la chaîne par l'entrée par défaut à un nombre entier afin que vous puissiez calculer les scores moyens:

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

Answer 3

Vous pouvez également utiliser la carte en calculant votre score.

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))) 

En outre, pouvez-vous s'il vous plaît dire comment fournissez-vous les entrées.
