File read( ) Method

File read( ) Method in Python 3

 The method read() reads at most size bytes from the file. If the read hits EOF before obtaining size bytes, then it reads only available bytes.

Syntax

fileObject.read( size );

Parameters

     size - This is the number of bytes to be read from the file.

Return Value

    This method returns the bytes read in string.

Example

Assuming that 'foo.txt' file contains the following text: This is 1st line This is 2nd line This is 3rd line This is 4th line This is 5th line

#!/usr/bin/python3 # Open a file fo = open("foo.txt", "r+") print ("Name of the file: ", fo.name) line = fo.read(10) print ("Read Line: %s" % (line)) # Close opened file fo.close()

When we run the above program, it produces the following result-

Name of the file: foo.txt Read Line: This is 1s
