Question

好的，我在做一个文本文件问题，并且90％的工作已经完成。尽管我在代码末尾打印了两个名称（都在不同的行上），但我正在尝试弄清楚如何在同一行上打印它们，特别是这样：(“ Best students：” name +“” + name）（可能有两个以上的名称，具体取决于文本文件中的文本）。我尝试使用end =“”将它们放在同一行上，并且它们之间有空格，这很好用。直到我不得不在它之前输入特定的文本，例如print（“ Best Students：”，name，end =“” ），但输出如下：

最佳学生：Michael Murphy最佳学生：John Kelly

预期产出：最佳学生：Michael Murphy，John Kelly 最佳成绩：89

任何对我有帮助的提示或想法都会受到赞赏。

谢谢

file = "students.txt"
with open(file,"r") as f:
q = []
for i in f:
  i = i.split()
  number = i[0]
  q += (number,)
highest = max(q)


with open(file,"r") as f:
for i in f:
   i = i.split()
   number = i[0]
   if highest == number:
     name = " ".join(i[1:])
     print("Best Students :",name,end=" ")
# print("Best Mark:",highest)
# Best Students : Michael Murphy, John Kelly
# Best mark: 89

Answer 1

with open(file,"r") as f:
    names = ""
    for i in f:
       i = i.split()
       number = i[0]
       if highest == number:
         if names != "": names += ", "
         names += " ".join(i[1:])

print("Best Students :",names)

像这样修改第二部分。我得到了这个输出

Best Students : Michael Murphy, John Kelly

Answer 2

这是另一个答案：

file = "students.txt"

def get_highest_grade(input):
  with open(input, "r") as f:
    q = []
    for i in f:
        i = i.split()
        number = i[0]
        q += (number,)
    highest = max(q)
 return (highest)

def get_best_students(input, grade):
  with open(input,'r') as f:
    student_names = ''
    for i in f:
        i = i.split()
        number = i[0]
        if grade == number:
          if student_names != '': student_names += ', '
            student_names += ' '.join(i[1:])

    print('Best Students: {} with a grade point of {}.'.format(student_names, grade))  

    # output 
    Best Students: Michael Murphy, John Kelly with a grade point of 89.

highest = get_highest_grade(file)
get_best_students(file,highest)

Answer 3

您可能会有一个标志，那就是我们只会在第一次迭代中打印出“最佳学生”。

file = "students.txt"
with open(file,"r") as f:
    q = []

    for i in f:
      i = i.split()
      number = i[0]
      q += (number,)
    highest = max(q)

studentFound = False
with open(file,"r") as f:
    for i in f:
        i = i.split()
        number = i[0]
        if highest == number:
            name = " ".join(i[1:])
            if(not studentFound):
                print("Best Students :",name,end=" ")
                studentFound = True
            else:
               print(",",name, end=" ")

    print("\nBest Mark:", highest)

结果

Best Students : Michael Murphy , John Kelly 
Best Mark: 89

如何将两个不同的行专门连接到文本文件中？
