Python--——檔案讀寫

一.檔案寫操作  import  pickle

三步:(1)開:檔案變數 = open(“檔案路徑檔名”,“wb”)

            (2)存:pickle.dump(“待寫入的變數”,“檔案變數“)

            (3)關:檔案變數.close()

程式碼如下:
 

Python 2.7.12 (default, Dec  4 2017, 14:50:18) 
[GCC 5.4.0 20160609] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import pickle
>>> game_data = {"position":"N2 E3","age":18}
>>> save_file = open("a.data","wb")
>>> pickle.dump(game_data,save_file)
>>> save_file.close()
>>> exit()

二.檔案讀操作 import pickle

三步:(1)開:檔案變數 = open(”檔案路徑檔名“,”rb“)

            (2)取:放內容的變數 = pickple.load(檔案變數)

            (3)關:檔案變數.close()

程式碼如下:
 

Python 2.7.12 (default, Dec  4 2017, 14:50:18) 
[GCC 5.4.0 20160609] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import pickle
>>> load_file = open("a.data","rb")
>>> load_game_data = pickle.load(load_file)
>>> load_file.close()
>>> load_game_data
{'position': 'N2 E3', 'age': 18}
