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.

- 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.
