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()
