屏幕上没有输出。当我正在阅读文件时，它没有提供输出

Question

import time


name = open('list.txt','a+')
print ("When file was opened the pointer was at", name.tell())
name.write('It\'s all about mindset.')
time.sleep(2)
print ("Writing your script.... Wait for some time...")
name.close()
name = open('list.txt','r')
string = name.read(0)
print('Final output is:'`
print (string)
name.close()

我目前正在学习python文件操作。上面的代码无法正常工作。它没有读取文件。

Answer 1

只需从0移除string = name.read(0)即可显示全部或写入大于0的数字。 应该显示字符的长度。
