python - 修复不显示两个值的 python 代码

Question

这是我作业的一部分，我之所以发布此内容是因为我对自己做错了什么感到困惑。

school = [['Abby Li'],         
['Ella Wang', 'Danielle Han','Katherine Zhang', 'Morgan Liu'], 
['Josh Li']       
]
def searchStudent(school1, lastname1):    
  firstname = "Not"    
  lastname = "Found"    

  for grade in school1:        
    for student in grade:            
      name = student.split();  
  
  if name[1] == lastname1:                
    firstname = name[0]                
    lastname = name[1]    

  return firstname, lastname

while (True):    
  search = input("Please enter last name to search:")   
  if (search == "exit"):
    break

  foundFirst, foundLast = searchStudent(school, search) 
  print("found student: ", foundFirst, foundLast)     
  print("")

这是我的代码，但每当我输入“Li”作为姓氏时，只有 Josh 出现，而​​ Abby 没有出现。有人可以帮我解决吗？非常感谢!

另外，如果上面没有显示，这里是它的链接:code

缩进使 if 语句脱离 for 循环

此外，如果您想打印所有匹配项，则需要存储所有匹配项，因此您需要诸如列表之类的东西!

school = [['Abby Li'],         
['Ella Wang', 'Danielle Han','Katherine Zhang', 'Morgan Liu'], 
['Josh Li']       
]
def searchStudent(school1, lastname1):    
  firstname = "Not"    
  lastname = "Found"    

  result = []

  for grade in school1:        
    for student in grade:            
      name = student.split();  
  
    if name[1] == lastname1:                
        firstname = name[0]                
        lastname = name[1]    
        result.append([firstname, lastname])

  return result

while (True):    
  search = input("Please enter last name to search:")   
  if (search == "exit"):
    break

  result = searchStudent(school, search) 
  for name in result: print("found student: ", name[0], name[1])   
  print("")

Please enter last name to search:Li
found student:  Abby Li
found student:  Josh Li

Please enter last name to search:exit
