今天就跟大家聊聊有關使用pickle怎么存儲dump和oad數據,可能很多人都不太了解,為了讓大家更加了解,小編給大家總結了以下內容,希望大家根據這篇文章可以有所收獲。
使用pickle模塊來dump你的數據
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))
打開man_data.txt,看結果:
?]q (X' Is this the right room for an argument?qX No you haven't!qX When?qX No you didn't!qX You didn't!qX You did not!qX= Ah! (taking out his wallet and paying) Just the five minutes.qX You most certainly did not!qX Oh no you didn't!q X Oh no you didn't!q X Oh look, this isn't an argument!qX No it isn't!qX It's just contradiction!q X It IS!qX You just contradicted me!qX You DID!qX You did just then!qX" (exasperated) Oh, this is futile!!qX Yes it is!qe.
把已存儲在man_data.txt上的二進制文件,恢復成可以讀的文件,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))
查看結果:
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? 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! (exasperated) Oh, this is futile!! Yes it is! >>> import os >>> os.getcwd() 'C:\\Users\\ThinkPad\\AppData\\Local\\Programs\\Python\\Python36-32' >>>
若是想保存new_man.txt到磁盤文件,可以加:
with open('new_man.txt','w') as new_man_file: nester.print_lol(new_man,fn=new_man_file)
