使用pickle模块来dump你的数据:对上篇博客里的sketch.txt文件:

import os
import sys
import pickle
 
man=[ ]
other=[ ]
try:
    data=open('sketch.txt')
    for each_line in data:
        try:
            (role,line_spoken)=each_line.split(':',1)
            line_spoken=line_spoken.strip()
            if role == 'Man':
                man.append(line_spoken)
            elif role == 'Other Man':
                other.append(line_spoken)
        except ValueError:
            pass
    data.close()
except IOError:
    nester.print_lol('The data file is missing!')
 
try:
    with open('man_data.txt','wb') as man_file:
      pickle.dump(man,man_file)
    with open('other_data.txt','wb') as other_file:
      pickle.dump(other,other_file)
    
 
 
except IOError as err:
  print('File error: ' + str(err))
except pickle.PickleError as perr:
  print('Pickling error: ' + str(perr))
 

打开man_data.txt,看结果:

?]q (X'  Is this the right room for an argument"  (exasperated) Oh, this is futile!!qX
  Yes it is!qe.

把已存储在man_data.txt上的二进制文件,恢复成可以读的文件,存放在new_man.txt中:

import nester
import os
import sys
import pickle
 
man=[ ]
other=[ ]
new_man=[ ]
 
try:
    data=open('sketch.txt')
    for each_line in data:
        try:
            (role,line_spoken)=each_line.split(':',1)
            line_spoken=line_spoken.strip()
            if role == 'Man':
                man.append(line_spoken)
            elif role == 'Other Man':
                other.append(line_spoken)
        except ValueError:
            pass
    data.close()
except IOError:
    print_lol('The data file is missing!')
 
try:
#    with open('man_data.txt','wb') as man_file:
#      pickle.dump(man,man_file)
#    with open('other_data.txt','wb') as other_file:
#      pickle.dump(other,other_file)
 
  with open('man_data.txt','rb') as man_file:
    new_man=pickle.load(man_file)
 
except IOError as err:
  print('File error: ' + str(err))
except pickle.PickleError as perr:
  print('Pickling error: ' + str(perr))

查看结果:

 RESTART: C:/Users/ThinkPad/AppData/Local/Programs/Python/Python36-32/chapter4-134-pickle.py 
> import nester
> nester.print_lol(new_man)
Is this the right room for an argument"htmlcode">
  with open('new_man.txt','w') as new_man_file:
    nester.print_lol(new_man,fn=new_man_file)

以上这篇使用pickle存储数据dump 和 load实例讲解就是小编分享给大家的全部内容了,希望能给大家一个参考,也希望大家多多支持。

P70系列延期,华为新旗舰将在下月发布

3月20日消息,近期博主@数码闲聊站 透露,原定三月份发布的华为新旗舰P70系列延期发布,预计4月份上市。

而博主@定焦数码 爆料,华为的P70系列在定位上已经超过了Mate60,成为了重要的旗舰系列之一。它肩负着重返影像领域顶尖的使命。那么这次P70会带来哪些令人惊艳的创新呢?

根据目前爆料的消息来看,华为P70系列将推出三个版本,其中P70和P70 Pro采用了三角形的摄像头模组设计,而P70 Art则采用了与上一代P60 Art相似的不规则形状设计。这样的外观是否好看见仁见智,但辨识度绝对拉满。
