How to Implement tab file operations in Python

The Python programming language is widely used and can be used in many fields to help developers meet certain requirements. For example, in file operations. Today, we will give you a detailed introduction of some specific operation skills for implementing the tab file operation in Python.

Python code example for implementing the tab file operation:

 
 

  
  
#-*-Coding: gbk -*-
  
  
Import OS
  
  
Class TABFILE:
  
  
Def _ init _ (self, filename, dest_file = None ):
  
  
Self. filename = filename
  
  
If not dest_file:
  
  
Self. dest_file = filename
  
  
Else:
  
  
Self. dest_file = dest_file
  
  
Self. filehandle = None
  
  
Self. content = []
  
  
Self. initflag = False
  
  
Self. column = 0
  
  
Self. row = 0
  
  
Self. data = []
  
  
Def Init (self ):
  
  
Try:
  
  
Self. filehandle = open (self. filename, 'R ')
  
  
Selfself. initflag = self. _ load_file ()
  
  
Except t:
  
  
Pass
  
  
Else:
  
  
Self. initflag = True
  
  
Return self. initflag
  
  
Def UnInit (self ):
  
  
If self. initflag:
  
  
Self. filehandle. close ()
  
  
Def _ load_file (self ):
  
  
If self. filehandle:
  
  
Selfself. content = self. filehandle. readlines ()
  
  
Self. row = len (self. content)-1
  
  
Head = self. content [0]. split ('\ t ')
  
  
Self. column = len (head)
  
  
For line in self. content:
  
  
# Remove the line feed at the end.
  
  
# Lineline = line-'\ n \ R'
  
  
Self. data. append (line. rstrip (). split ('\ t '))
  
  
Return True
  
  
Else:
  
  
Return False
  
  
Def GetValue (self, row, column ):
  
  
If 0 <row <self. row and 0 <column <self. column:
  
  
Return self. data [row] [column-1]
  
  
Else:
  
  
Return None
  
  
Def SetValue (self, row, column, value ):
  
  
If 0 <row <self. row and 0 <column <self. column:
  
  
Self. data [row] [column] = value
  
  
Else:
  
  
Return False
  
  
Def SaveToFile (self ):
  
  
Filewrite = open (self. dest_file, 'w ')
  
  
If not filewrite:
  
  
Return False
  
  
Sep_char = '\ t'
  
  
For line in self. data:
  
  
Filewrite. write (sep_char.join (line) + '\ n ')
  
  
Filewrite. close ()
  
  
Return True
