Example

The following example shows the usage of readline() method.

#!/usr/bin/python

# Open a file

fo = open("foo.txt", "r")

print "Name of the file: ", fo.name

# Assuming file has following 5 lines

# This is 1st line

# This is 2nd line

# This is 3rd line

# This is 4th line

# This is 5th line

line = fo.readline()

print "Read Line: %s" % (line)

line = fo.readline(5)

print "Read Line: %s" % (line)

# Close opened file

fo.close()

Let us compile and run the above program, this will produce the following result:

Name of the file: foo.txt

Read Line: This is 1st line

Read Line: This

file.readlines([sizehint])

Description

The method readlines() reads until EOF using readline() and returns a list containing the lines. If the

optional sizehint argument is present, instead of reading up to EOF, whole lines totalling approximately

sizehint bytes (possibly after rounding up to an internal buffer size) are read.

Syntax

Following is the syntax for readlines() method:

fileObject.readlines( sizehint );

Parameters

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

Return Value

This method returns a list containing the lines.

Example
