本文實例為大家分享了python文件寫入write()的操作的具體代碼，供大家參考，具體內容如下

filename = 'pragramming.txt'

with open(filename,'w') as fileobject: #使用‘w'來提醒python用寫入的方式打開

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'來提醒python用附加模式的方式打開

fileobject.write('\ni an superman.')

代碼中的filename如果沒有這個文件，python會自己新建一個。

json文件的寫入和讀取：

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)#寫入json文件

write_json()

def read_json():

with open(filename) as pf:

numbers = json.load(pf)#讀取json文件

print(numbers)

read_json()

訓練：

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的方式打開寫入時會覆蓋原有記錄，而以a打開不會

json.dump(username,fp)

print('hello! '+username.title())

else:

active = false

remember_me()
