tutorial on using the Read () method for manipulating files in Python

The Read () method reads the file size of bytes. If the read hit gets the EOF size byte, then it can only read the available bytes.
Grammar

The following is the syntax for the Read () method:

Fileobject.read (size);

Parameters

• Size-This is the number of bytes that can be read from the file.

return value

This method returns the number of bytes in the read string.
Example

The following example shows the use of the Read () method.

#!/usr/bin/python# Open a filefo = open ("Foo.txt", "rw+") print "Name of the file:", fo.name# assuming file has following 5 lines# This was 1st line# this is 2nd line# This is 3rd line# This is 4th line# this is 5th lineline = fo.read (+) print " Read line:%s "% (line) # Close opend filefo.close ()

When we run the above program, it produces the following results:

Name of the file:foo.txtRead line:this is 1s
