This article describes two simple ways to implement secure switch files in Python. Share with everyone for reference, as follows:

The following code is implemented by Python3.3Test.

mode1:

try:
  file = open('config.ini', 'w')
  print("It's a text file", file=file)
except IOError as err:
  print('File error: ') + str(err))

  if 'file' in locals():
    file.close()

    print("It's a text file", file=file)
except IOError as err:
  print('File error: ') + str(err))
