  • Close Files

 

 

 

Reading Text Files 

 
  • To read any files, we have to open the file first. We use the open() function to open file.
  • open() method takes two-parameter ( file name – mode ). To read a file we use the r mode.
  • There are two ways to open a file. The first one is located in the same folder and
    the second one is located in a different location.

 

Example :

This program opens a file from located in the same folder.

Close Files


After open and do some tasks on file, we have to close the file.  To close file we use the close() function.

Example :

 

Output Of The Program : 

 

 

 

Example : 

  • Instead of closing files with the close() method , we can use the with method.
  • This ensures that the file is closed when the block inside the with statement is exited.
