本文实例为大家分享了python/' target='_blank'>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 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()
训练:
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()
