使用pickle存储数据dump 和 load实例讲解

import pickle
 
man=[ ]

try:
    data=open('sketch.txt')
    for each_line in data:

Is this the right room for an argument?
No you haven't!
When?
No you didn't!
You didn't!
You did not!
Ah! (taking out his wallet and paying) Just the five minutes.
You most certainly did not!
Oh no you didn't!
Oh no you didn't!
Oh look, this isn't an argument!
No it isn't!
It's just contradiction!
It IS!
You just contradicted me!
You DID!
You did just then!
