File readlines( ) Method in Python 3
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.
An empty string is returned only when EOF is
encountered immediately.
Syntax
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
Assuming
that 'foo.txt' file contains 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.readlines()
print
("Read Line: %s" % (line))
line =
fo.readlines(2)
print
("Read Line: %s" % (line))
# Close
opened file
fo.close()
|
When we run above program, it produces following
result-
Name of
the file: foo.txt
Read
Line: ['This is 1st line\n', 'This is 2nd line\n',
'This is 3rd line\n', 'This is 4th line\n',
'This is 5th line\n']
Read
Line:
