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()
