Deleting from file in python. OSError: [WinError 123] The filename, directory name, or volume label-CodePudding

Trying to delete a line from my file in python, and its throwing me this error. I have a student database, I want to delete a student/line that has the corresponding student id. E.g., line = 'SanVin22\tSanji\tVinsmoke\tWellington'. id is the inputted id.

def DelStudent(self, data):
        
  self = id

  with open(data, "r ") as datafile:
    for line in datafile:
      datum = line.split()
      if datum[0] == id:
        os.remove(line)       
  pass

Error is:

   os.remove(line)
    OSError: [WinError 123] The filename, directory name, or volume label syntax is incorrect: 'SanVin22\tSanji\tVinsmoke\[email protected]\tWellington\t'

I've tried replacing os.remove(line) with datafile.write(line), as all of the tutorials I've seen online, but that ends up deleting every list in the database.

CodePudding user response：

If the idea is to delete the line with the given id, then gather up all of the non-matching lines (i.e. those that we want to keep) and then write them back to the original file.

def DelStudent(self, data):
    new_lines = []
    with open(data, "r ") as datafile:
        for line in datafile:
            datum = line.split()
            if datum[0] != id:
                new_lines.append(line)
    with open(data, "w") as datafile:
        for line in new_lines:
            datafile.write(line)
