Python file processing

1. Create File:

f = File (' myfile.txt ', ' W ') #myfile as file name, W is write permission.

F. Write ("Hello world!") #hello world! is the contents of the file to be written.

F.close () #文件打开后一定要记得关闭 because an error occurs when another program opens the file again.

Permissions for files are also:

w+

r+

A +

WB,RB binary form read and write files

EG1: Real-time Write

Import time

f = File ("F_test.txt", ' W ')

For I in range (15):

Time.sleep (1) #休眠一秒

F.write (' The%s loops\n '% i)

F.flush () #没循环一次 that the data in memory is written to the hard disk.

Time.sleep #循环结束, sleeps 10 seconds

F.close ()
