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()
