IO编程

• 打开文件

1 F=open(r'c:\text\f.txt','r') View Code

• 文件读取

1 try: 2 F=open(r'c:\text\f.txt', 'r') 3 print(F.read()) 4 finally: 5 if F: 6 F.close() 7 ___________________________等于 8 with open(r'c:\text\f.txt', 'r') as f: 9 print f.read() View Code

• 文件写入
• 1 with open(r'fujun.txt', "wb") as f: 2 f.write("shushed")

   

• 序列化操作
• 1. try: 2. import cPickle as pickle 3 4 except ImportError : 5 import pickle

   

  1 import cPickle as pickle 2 3 d=dict(h="首页", t="title") 4 pickle.dumps(d) 5 6 7 open open(r"f.txt", "ab") as f: 8 9 pk=pickle.dumps(d, f)
  f.close()

   

  1 with open(r'f.txt', 'wb') as f: 2 3 pickle.load(f) 4 f.close() 5
