python - 通过循环文本文件找到字符串后进入下一次迭代？

Question

我正在尝试迭代组织如下的文本文件:

学生 1 姓名
一年级学生
学生2姓名
2年级学生
...
学生N姓名
N年级学生

当我在一行中找到学生姓名后，如何更改他的成绩？这是我想出的代码，但我不知道如何更改学生姓名后面的行。

gradebook = open('gradebook.txt', 'r')  
studentName = input("What is the students name?")
for line in gradebook:
    if line.rstrip() == studentName:
        #I want to insert code here that would change the text on the line 
        #after the line where studentName is found.
    else:
        print("The student was not found.")

Answer 1

 temp = []
 with open('data', 'r') as f:
    for line in f:
        if "Student 2" in line:
            try:
                # get Student 2 grade
                line = next(f)
                temp.append(changed_line)  
            # just in case Student name was the last line of the file
            except StopIteration:
                break
        else:
             temp.append(line)

   # save you changes back to the file
   with open('data', 'w') as f:
       for line in temp:
         f.write(line)
