read file into list of lists

[antar2]

Hello,

I can not find out how to read a file into a list of lists. I know how
to split a text into a list

sentences = line.split(\n)

following text for example should be considered as a list of lists (3
columns and 3 rows), so that when I make the print statement list[0]
[0], that the word pear appears


pear noun singular
books nouns plural
table noun singular

Can someone help me?

Thanks

from __future__ import with_statement

res = []
with open("sentences .txt","r") as f:
sentences = [elem for elem in f.read().split( '\n') if elem]
for sentence in sentences:
res.append(sent ence.split())

print res
=============== =============== =============== =============== ===

You can use split again, using ' ' or nothing(default s to whitespace
characters) as separator,
like this:

>>text = """pear noun singular

books nouns plural
table noun singular"""

>>words = [ x.split() for x in text.split('\n' ) ]
>>print words

[['pear', 'noun', 'singular', ''], ['books', 'nouns', 'plural', ''],
['table', 'noun', 'singular']]

lofl = [line.strip().sp lit() for line in the_opened_file]

class Table(object):

def __init__(self, text=None):
self.rows = []
if text:
self.write(text )

def write(self, text):
self.rows.exten d(line.split() for line in text.splitlines ())

def read(self):
return '\n'.join(' '.join(row) for row in self.rows)

def __getitem__(sel f, i):
return self.rows[i]

def __iter__(self):
return iter(self.rows)

table = Table()

table.write('ap ple orange coconut')

print table[0][1]

print table.read()

table.write('cl ematis rose lily')

print table[1][2]

print table.read()


for row in table:
print row



(If you have quoted items, it is more difficult)

File objects are themselves iterable, returning one line per iteration. So a
simple approach is:

>>table = [line.split() for line in open('sentences .txt')]
>>table[0][0]

'pear'
