本文实例为大家分享了python文件写入write()的操作的具体代码,供大家参考,具体内容如下

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.')

代码中的filename如果没有这个文件,python会自己新建一个。

json文件的写入和读取:

import json

filename = '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()

训练:

import json
def 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 = False
remember_me()
