Python简单实现安全开关文件的两种方式

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

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