我有一個文本文件(成績),我給了姓,名和成績。我需要閱讀它們,將它們分配給變量,並將它們寫入不同的文本文件(Graded)。我是初學者,這是我的第一個任務。我知道有些錯誤,但我想知道的最重要的事情是如何讀入然後寫入文件,以及如何將3個變量合併爲一個。在一個txt文件中讀取python並將字符串分配給組合變量(連接)

class Student: 
    def __init__(self, str_fname, str_lname, str_grade): 
     """Initialization method""" 
     self.str_fname = str_fname 
     self.str_lname = str_lname 
     self.str_grade = str_grade 

    @property 
    def str_fname(self): 
     return self.str_fname 

    @str_fname.setter 
    def str_fname(self, str_fname): 
    """Setter for first name attribute""" 
     if not isinstance(str_fname, str): 
      #This is not a string, raise an error 
      raise TypeError 
     self.fname = str_fname 

    @property 
    def str_lname(self): 
     """Return the name""" 
     return self.str_lname 

    @str_lname.setter 
    def str_fname(self, str_lname): 
     """Setter for last name attribute""" 
     if not isinstance(str_lname, str): 
      # This is not a string, raise an error 
      raise TypeError 
     self.str_lname = str_lname 

    @property 
    def str_grade(self): 
     """Return the name""" 
     return self.str_grade 

    @str_grade.setter 
    def str_grade(self, str_grade): 
     """Setter for grade attribute""" 
     if not isinstance(str_grade, str): 
      # This is not a string, raise an error 
      raise TypeError 
     self.str_grade = str_grade 


Student = str_lname+str_fname+str_fname 
f = open('Grades.txt', 'r') 
g = open('Graded.text', 'w') 
f.read() 
g.write()
