python文件写入write（）的操作

filename = 'pragramming.txt'with open(filename,'w') as fileobject: #使用‘w'来提醒python用写入的方式打开  fileobject.write('I love your name!'           '/nI love your cloth!'           '/nI love your shoes!'           '/nI love your hair!')with open(filename,'a') as fileobject: #使用‘a'来提醒python用附加模式的方式打开  fileobject.write('/nI an superman.')

import jsonfilename = 'number.json'def write_json():  numbers = [1,2,3,4,5,6,7,8,9,10]  with open(filename,'w') as fp:    json.dump(numbers,fp)#写入json文件write_json()def read_json():  with open(filename) as pf:    numbers = json.load(pf)#读取json文件    print(numbers)read_json()

import jsondef remember_me():  active = True  while active:    for i in range(5):      if i < 4:        username = input('Please enter your name:')        filename = 'name.json'        with open(filename,'w') as fp:#以w的方式打开写入时会覆盖原有记录，而以a打开不会          json.dump(username,fp)          print('Hello! '+username.title())      else:        active = Falseremember_me()
