Python file operations

Codecs module: Handle garbled problem during file operation.

F=codecs.open (' Fxh.txt ', ' r+ ') #打开文件

Open mode:

R, W, A, B, r+, w+ ....

Common methods:

Read () reads the contents of the file

Write () writes the content, must pass in the string

WriteLine () write content, must pass in a sequence

Next line after next () cursor

Seek () sets the position of the cursor

Tell () to see where the cursor is

Flush () flush to disk

Name File name

Closed whether the shutdown is off or true

To open a file using with: (a file that is opened with the with does not have to be closed manually)

Eg: Prints a specific line of the file.

With Codecs.open (' fxh.txt ', ' r+ ') as FD:
    #text =fd.read ()
    For Line,value in Enumerate (FD):
        if line = = 2-1:
            Print (value)
The above implementations can also be implemented using a single module:

Import Linecache
Test=linecache.getline (' Fxh.txt ', 2)
Print (test)
